When an agent views a group of images, they show as a grid in the response. A click opened one image alone, so the arrow keys and the previous/next buttons in the preview did nothing.

The viewed-images row is now a gallery. The preview opens at the image you clicked and the arrow keys and buttons step through the rest of the row.

Before	After

Proof: the new browser test fails on main and passes here. In the dev app, a click on image 2 of 4 showed 2/4, then ArrowRight 3/4, the Previous button 2/4, ArrowLeft 1/4.

Walkthrough

The viewed-images row adds a data-image-gallery attribute. A browser test checks that clicking the second image calls onImageExpand with all three images and index 1.

Changes: Viewed-image gallery expansion

Layer / File(s)	Summary
Gallery marker and expansion test apps/web/src/components/chat/TimelineWorkEntryRow.tsx, apps/web/src/components/chat/MessagesTimeline.browser.test.tsx	The viewed-images container gains a data-image-gallery attribute. The browser test checks that clicking the second image calls onImageExpand once with all three images and index 1. The test also renames the mocked asset URL state and updates the audio test setup and cleanup.

Change: Bug fix

Suggested labels: bugfix

Suggested reviewers: maria-rcks, fedeinfe

Merge Risk: Low · up to 841d0

Image galleries now open from the viewed-images row and support arrow and button navigation. An image whose asset URL has not yet loaded can be missing from the gallery if a neighboring image is clicked early. This matches existing gallery behavior and is minor, so it is mergeable with owner awareness.

- Line 183: Update the image gallery associated with the data-image-gallery
container in TimelineWorkEntryRow so images with pending asset URLs are included
when a preview opens, or refresh the preview when their URLs resolve; ensure
gallery navigation can reach those images once loaded.
