Image Gallery

Display and browse image collections

What it solves

A Image Gallery pattern helps teams create a reliable way to help users browse several related images without losing orientation, context, or performance. It is most useful when teams need portfolio and gallery pages. Compared with adjacent patterns, this pattern should reduce friction without hiding the state, rules, or recovery paths people need to keep moving.

When to use

• Portfolio and gallery pages
• Product image collections
• Documentation screenshots and walkthroughs

When to avoid

• Use a simpler image, link, or file input if full media handling is not actually needed.
• Avoid rich custom controls when browser-native behavior is enough for the task.
• Do not assume network-heavy media is appropriate for every audience or context.

Implementation workflow

1. Confirm the pattern matches the problem and constraints before copying the example.
2. Start from the anatomy and examples in references/pattern.md, then choose the smallest viable variation.
3. Apply accessibility, performance, and interaction guardrails before layering visual polish.
4. Use the testing guidance to verify behavior across keyboard, screen reader, responsive, and failure scenarios.

Accessibility guardrails

Keyboard Interaction

• Verify that image gallery can be completed using keyboard alone.
• Keep focus order logical when the pattern opens, updates, or reveals additional UI.
• Preserve a visible focus state that is still readable at high zoom.

Screen Reader Support

• Use semantic elements first, then add ARIA only where semantics alone are not enough.
• Announce state changes such as errors, loading, or completion in the right place and with the right politeness.
• Connect labels, hints, and status text with aria-describedby or structural headings when useful.

Visual Accessibility

• Do not rely on color alone to convey severity, completion, or selection state.

Common mistakes

Treating media as decoration only

The Problem: Important uploads and playback flows break when the design assumes the media is just visual garnish.

How to Fix It? Design state, metadata, and controls as first-class parts of the pattern, not as overlays added later.

Skipping fallback behavior

The Problem: Different devices support different codecs, capture flows, and bandwidth envelopes.

How to Fix It? Plan graceful fallbacks for unsupported APIs, low data conditions, and failed loads.

Forgetting accessibility artifacts

The Problem: Media patterns become exclusionary quickly when captions, transcripts, alt text, or visible status are missing.

How to Fix It? Treat alternate access paths as part of the core experience, not as post-launch polish.
