+- The image view was refactored to match the gallery layout and styling; `viewer/templates/image_view.html` now uses the shared `viewer/static/css/styles.css` file and Bootstrap/Font Awesome includes like `gallery_view.html`.
+- `_render_image` in `viewer/views.py` now exposes additional context keys used by the template and tests: `prev_url`, `next_url`, `prev_thumb`, `next_thumb`, `back_url`, `back_thumb`, `home_url`, `home_thumb`, and `image_meta` (dictionary with `filename`, `width`, `height`, `filesize`, `created`, `modified`). Agents modifying image-view behavior should update tests in `viewer/test.py` as well.
+- The top-bar sort button for the image view was replaced by an Info button (`fa-circle-info`) which shows a dropdown containing image metadata. The dropdown is vertically scrollable for long content.
+- The displayed main image now uses the same drop shadow and rounded corners as thumbnails (styles added to `viewer/static/css/styles.css`).
