 - **URI scheme**: `vscode-image-carousel` (registered in `Schemas` in `src/vs/base/common/network.ts`) — used for `EditorInput.resource` identity.
 - **Direct editor input**: Callers create `ImageCarouselEditorInput` with a collection and open it directly via `IEditorService.openEditor()`.
-- **Image extraction**: `IImageCarouselService.extractImagesFromResponse()` extracts images from chat response tool invocations. The collection ID is derived from the chat response identity (`sessionResource + responseId`).
+- **Image extraction**: `IImageCarouselService.extractImagesFromResponse()` extracts images from chat response tool invocations into a **sections-based** collection. All images from a single response are grouped into one section. The collection title is the user's chat request message. Each image caption is derived from the tool's `pastTenseMessage` (preferred) or `invocationMessage`.

 ### DOM & rendering
 
 - **DOM construction**: Uses the `h()` helper from `vs/base/browser/dom` with `@name` references for declarative DOM — no imperative `document.createElement` calls.
+- **Bottom bar**: Caption and thumbnail sections are wrapped in a `div.bottom-bar` flex column below the image area.
 - **Stable DOM skeleton**: Builds DOM once per `setInput()`, updates only changing parts to avoid flash on navigation.
 - **Blob URL lifecycle**: Main image URLs tracked in `_imageDisposables` (revoked on nav), thumbnails in `_contentDisposables` (revoked on `clearInput()`).
 - **Focus border suppressed**: The slideshow container uses `outline: none !important` on `:focus` / `:focus-visible` to override the workbench's global `[tabindex="0"]` focus styles.
