This guide focuses on a practical design decision that can improve how visitors understand and use a website. Start from the page’s purpose, then review the result with real content and common screen sizes.
1. Choose a gallery purpose and edit the selection
Decide whether the gallery documents a project, presents a collection, or helps visitors compare examples. Select images that support that purpose instead of uploading every available asset.
Lead with an image that establishes the subject, then choose a sequence that adds useful detail. Remove near-identical frames unless the comparison itself matters to the story.
2. Write captions and alt text for different jobs
Use captions for context such as project name, date, location, or photographer credit. Write alt text for informative images based on the detail a visitor needs; do not copy the caption word for word.
For decorative images, use the appropriate empty alternative text. Confirm image rights and permissions before publication, and do not place essential instructions only inside an image.
3. Prepare crops and file sizes for the layout
Check that the subject remains visible in the intended crop and that portrait and landscape images are not forced into an unsuitable frame. Keep important details away from edges that may be cut off.
Use appropriately sized WebP or other supported files and review loading on a real page. A gallery should not make visitors wait for large originals when smaller display files will work.
4. Test the gallery as part of the full page
Review the order, spacing, captions, and mobile presentation together with the surrounding copy. Check zoom and keyboard behavior in the published output if the gallery uses interactive controls.
Update the gallery when project facts, rights, or availability change. For help selecting assets before building, see the guide to choosing website images.
