It now includes a lightbox. Core handles columns, crops, ordering, captions, links, resolutions, and consistent aspect ratios. It does not provide documented album taxonomies, visitor filters, proofing, or dynamic media queries. ## Understand the Gallery block A Gallery block contains individual Image blocks. The parent controls collection-wide layout and behaviour. Each child Image block retains image-specific controls. Some Image options differ inside Gallery. The [official Gallery block guide](https://wordpress.org/documentation/article/gallery-block/) documents current layout, links, lightbox, movement, captions, and styles. ## Map Gallery ownership - Gallery owns collection layout. - Gallery owns column count. - Gallery owns shared crop behaviour. - Gallery owns shared aspect ratio. - Gallery owns collection link behaviour. - Image blocks own individual media. - Image blocks own individual captions. - Media Library owns attachment records. - The theme owns default presentation. Select the correct owner before editing. Parent and child toolbars intentionally differ. ## Create a simple gallery 1. Add the Gallery block. 2. Upload or select images. 3. Arrange the editorial order. 4. Choose a column count. 5. Choose crop and aspect settings. 6. Add appropriate captions and alternatives. 7. Choose link or lightbox behaviour. 8. Preview several viewport widths. Start with real images. Placeholder dimensions conceal crop, quality, and wrapping problems. ## Choose the column count Current core supports one through eight columns. The image count sets the practical maximum. More columns create smaller thumbnails. Fewer columns give each image greater visual weight. Choose from image detail and reading context. Do not maximise columns merely because available. ## Understand responsive columns The published gallery adapts through core and theme styles. Exact breakpoints can differ. Core does not expose every viewport’s column count through one universal settings interface. Test desktop, tablet, narrow mobile, and zoomed layouts. Editor previews remain approximations. ## Choose image resolution The Resolution setting selects available generated image sizes. Choices depend on media and theme support. Use enough pixels for the displayed slot. Full-size files are rarely necessary for thumbnails. Test sharpness on dense screens. Balance visual quality against downloaded bytes. ## Understand Crop images to fit Cropping makes varied images appear consistently shaped. It can remove meaningful edge content. Disable cropping when complete compositions matter. Expect uneven row heights or whitespace. Preview every crop before publishing. Automated fitting cannot understand the photograph’s subject. ## Choose a shared aspect ratio Current Gallery settings can apply one aspect ratio across images. This supports regular layouts. A shared ratio still crops diverse originals. Portraits and panoramas may lose important context. Group compatible compositions where possible. Mixed subjects create avoidable crop compromises. ## Reorder images deliberately Move images through the toolbar, drag handles, or [List View](https://wpblocksuite.com/blog/use-wordpress-list-view-complex-pages/). Build a meaningful sequence. Order can communicate time, process, location, or argument. Random placement weakens that meaning. Review keyboard and reading order after rearrangement. Visual position should match underlying order. ## Understand Randomize order Randomize changes the published order while retaining editor order. Every visit may present different sequencing. Do not randomize narratives, processes, or ranked images. Their sequence carries meaning. Random order can distribute exposure across equivalent images. It complicates testing and references. ## Add individual captions Each nested Image block can carry its own caption. Use captions for visible image context. Keep captions concise and specific. Do not repeat nearby prose or alternative text mechanically. Check legibility over varied image tones. Theme caption placement can affect contrast. ## Add a gallery caption The parent Gallery block can have one collection caption. Use it to explain shared context. State location, event, scope, or sequence where useful. Avoid duplicating the section heading. Individual captions still own image-specific facts. Keep parent and child roles distinct. ## Write alternative text individually Alternative text belongs to each image’s purpose. The Gallery block cannot write it collectively. Describe useful information absent from nearby text. Mark genuinely decorative images appropriately. Do not paste filenames or keyword lists. Context determines the useful description. ## Choose attachment-page links Attachment-page links open WordPress pages for individual media. Those pages may include metadata and comments. Use them only when attachment pages provide intentional value. Empty pages create pointless detours. Check theme templates and indexing policy. Attachment behaviour varies across site configurations. ## Choose media-file links Media-file links open the image file directly. Visitors leave the surrounding gallery context. This can support downloads or full-resolution inspection. It is not a coordinated gallery experience. Opening new tabs requires clear purpose. Avoid surprising visitors for ordinary image viewing. ## Use Enlarge on click Current core can enlarge gallery images in a lightbox. Visitors remain on the page. The lightbox includes navigation through gallery images. It also provides closing controls. This covers many simple viewing needs. It does not create albums or visitor filtering. ## Choose lightbox navigation labels Current controls can show icons, text, or both. The setting appears with Enlarge enabled. Text can clarify unfamiliar controls. Icons can reduce visual width but require clear meaning. Test every button’s accessible label. Visual presentation cannot prove assistive output. ## Understand lightbox boundaries A lightbox enlarges selected media. It does not make the gallery a content slider. Core controls remain focused on viewing images. Complex slide content needs another component. Do not add another lightbox plugin without testing core. Duplicate interactions can conflict. ## Choose no link when appropriate Images need no click behaviour when displayed detail is sufficient. Static presentation removes ambiguity. A cursor should not imply unavailable interaction. Check theme hover effects on unlinked images. No link also reduces navigation complexity. Simplicity can serve editorial galleries well. ## Understand album limitations Core Gallery represents one collection inside one post. Documented controls provide no nested album system. Large archives may need named albums, hierarchy, covers, and archive navigation. Define those needs precisely. Separate pages can serve a few albums. Link them through ordinary navigation. ## Understand taxonomy limitations Core does not expose Gallery categories or tags for visitor browsing. Images remain attachments. A taxonomy system needs data ownership and archive templates. It exceeds a static collection block. Do not create taxonomy merely because many images exist. Confirm recurring discovery tasks first. ## Understand filtering limitations Documented core controls offer no visitor filters. Every gallery image appears together. Small collections need no filters. Strong curation and sequencing usually provide enough structure. Large portfolios may need topics, dates, locations, or media filters. Specify combination behaviour. ## Understand dynamic-source limitations Core Gallery displays selected images. It does not query attachments dynamically through its documented controls. New uploads will not automatically join an existing static gallery. Editors must add them. Dynamic sources require query rules, ordering, caching, and empty states. They need explicit ownership. ## Understand proofing limitations Core provides no client approval, favourite, comment, or selection workflow within Gallery. Photographic proofing involves identities, permissions, records, downloads, and delivery. It is an application workflow. Do not expose private work through ordinary public galleries. Choose access controls deliberately. ## Understand ecommerce limitations Gallery images are not products. Core provides no prices, variations, stock, carts, or checkout. Linking images toward product pages can work for curated features. Maintenance remains manual. A product catalogue needs commerce data and templates. Do not rebuild those responsibilities with captions. ## Understand masonry limitations Core documentation describes columns, cropping, and aspect ratios. It provides no dedicated masonry setting. Masonry preserves varied heights while packing columns. Reading order can become less obvious. Use consistent ratios when regular grids work. Add masonry only for a demonstrated visual need. ## Understand pagination limitations Core renders the selected collection together. It provides no gallery-specific pagination controls. Large collections increase downloads, markup, and browsing effort. Curate aggressively before adding pages. Pagination needs stable URLs, ordering, and shared state. Those decisions belong beyond visual layout. ## Plan image performance Each image adds network and decoding work. Gallery length multiplies that cost quickly. Use suitable dimensions, modern formats, and sensible compression. Keep originals available where necessary. Measure the public page with production images. Empty blocks prove no performance outcome. ## Use lazy loading appropriately WordPress and browsers can [lazy-load](https://wpblocksuite.com/blog/lazy-loading-images-wordpress-blocks/) eligible images. Above-the-fold images may need different treatment. Do not assign every image high priority. Competing priorities can delay truly important content. Test scrolling and layout stability. Delayed images should not create disruptive movement. ## Avoid uploading oversized originals needlessly Huge originals consume storage and processing time. They may also increase accidental full-size downloads. Retain archival originals outside WordPress when appropriate. Publish sizes based on real display needs. Image quality requirements vary by photography and audience. Test representative detailed subjects. ## Plan media ownership Record creators, licences, permissions, subjects, and usage limits. Gallery layout cannot provide rights. Use Media Library fields consistently. File names alone rarely preserve sufficient provenance. Remove expired assets from every placement. Deleting one Gallery block may not delete attachments. ## Plan replacement behaviour Replacing an individual image changes that Image block. Check captions, alternatives, links, and crops. A replacement with another ratio can alter the visual balance. Preview every breakpoint. Confirm usage rights for the replacement. Technical compatibility does not grant permission. ## Avoid duplicate image records Repeated uploads create duplicate attachments and inconsistent metadata. Reuse the correct Media Library item. Do not reuse one record for a materially different edit. Alternative text may require contextual changes. Define file naming and replacement rules. Media libraries deteriorate quietly without governance. ## Use List View for complex galleries List View reveals the Gallery parent and nested Image blocks. It supports precise reordering. Select the parent for shared settings. Select a child for image-specific changes. Rename nothing mentally. The hierarchy already explains which controls should appear. ## Create a reusable gallery pattern A pattern can preserve heading, introduction, Gallery settings, and supporting copy. Replace placeholder media carefully. Do not sync changing image collections accidentally. Shared updates can affect unrelated pages. Patterns should define structure, not force every collection into one editorial shape. ## Test keyboard interaction 1. Tab through linked images. 2. Confirm focus remains visible. 3. Open the core lightbox. 4. Navigate forward and backward. 5. Close the lightbox. 6. Confirm focus returns logically. 7. Repeat across several images. Test the published frontend while logged out. Editor controls are unrelated to visitor interaction. ## Test touch interaction Use real mobile browsers. Check taps, swipes where supported, controls, and dismissal. Captions and controls must not overlap important image regions. Rotate the device when relevant. Slow networks expose loading states. A blank overlay provides poor feedback. ## Test zoom and reflow Zoom the page and lightbox controls substantially. Text and buttons must remain available. Long captions should wrap without hiding controls. Horizontal page scrolling needs investigation. Theme styles can affect both states. Test Gallery and lightbox separately. ## Test printing and exports Printed galleries may split rows or omit linked targets. Check representative print output. Email and feed tools can alter Gallery markup. Inspect important distribution channels separately. Lightbox behaviour cannot travel into static formats. Ensure the visible gallery remains meaningful. ## Diagnose missing Gallery controls 1. Select the Gallery parent. 2. Open the Settings tab. 3. Check the installed WordPress version. 4. Confirm theme support. 5. Check block restrictions. 6. Test without editor customisations. Selecting an Image child shows another toolbar. That difference is expected. ## Diagnose broken crops Check parent crop and aspect settings first. Then inspect each source image’s composition. Disable cropping temporarily to confirm the cause. Do not hide subjects behind styling patches. Replace incompatible images or regroup them. One ratio cannot serve every composition equally. ## Diagnose lightbox conflicts Check whether another plugin adds image overlays. Duplicate handlers can open multiple interfaces. Disable enhancements on staging and test core alone. Clear relevant caches afterwards. Choose one lightbox owner. Competing interactions rarely improve the visitor experience. ## Diagnose incorrect image order Check Randomize order before rearranging manually. Published order can intentionally differ from editor order. Disable randomisation for narratives and referenced sequences. Then reorder through List View. Clear page caches and retest publicly. Cached markup can preserve an earlier order. ## Know when separate pages work better Several small collections can live on separate descriptive pages. Ordinary navigation then supplies hierarchy. This approach needs no album plugin. It also gives each collection unique context. A specialist archive becomes useful when collection count and discovery tasks grow substantially. ## Know when a specialist gallery helps Albums, filtering, proofing, dynamic sources, masonry, pagination, or commerce can justify extension. Define the exact workflow before comparing products. Test free versions with production-like images. Our [Galleryberg Pro](https://wpblocksuite.com/plugins/galleryberg-pro/) page lists what its version covers. Check deactivation output and migration options. Image archives often outlive their original plugin. ## Know when core remains better A small static collection needs no album database, filters, or scripts. Core stays understandable. Its native lightbox covers ordinary enlargement. Additional machinery may duplicate existing controls. This is the honest weak case. Start with core and earn every dependency. ## Use the Gallery decision checklist 1. Define the collection’s purpose. 2. Choose meaningful editorial order. 3. Select sensible columns. 4. Review every crop. 5. Choose appropriate resolutions. 6. Write contextual captions and alternatives. 7. Choose one link behaviour. 8. Test the core lightbox. 9. Test keyboard and touch use. 10. Measure real image performance. 11. Record media rights and ownership. 12. Extend only for proven workflows. ## Frequently asked questions Does core WordPress Gallery include a lightbox? Yes. Enlarge on click opens images and supports gallery navigation. How many Gallery columns can core provide? Current documented controls allow one through eight, limited by image count. Can visitors filter a core Gallery? No. Current documented core controls include no visitor filter system. Can Gallery images appear in random order? Yes. Randomize changes published order while editor order remains unchanged. When should I use a gallery plugin? Use one when proven workflows require albums, filters, proofing, or dynamic sources. ## The verdict Verdict **Use core for curated collections:** columns, crops, captions, links, and lightbox cover ordinary galleries. **Extend from workflows:** albums, filters, proofing, dynamic sources, and commerce require responsibilities beyond layout. Core Gallery is the sensible default for simple collections. Test free specialist blocks first.
