 ### Gallery Data Flow

 **`gallery_view()` function** (viewer/views.py:65-189) handles both:
 
 1. **Directory browsing** when path points to folder:
-   - Lists subdirectories and images
-   - Supports search with recursive directory scanning (viewer/views.py:32-52)
-   - Paginates images at 28 per page (7 columns × 4 rows)
-   - Converts flat image lists to table rows for HTML rendering
+    - Lists subdirectories and images
+    - Supports search with recursive directory scanning (`viewer/directory.py:do_recursive_search`)
+    - Does not use server-side pagination; the gallery returns full image lists and templates render them in a grid
+    - Converts image lists to structured context used by templates
 
 2. **Image viewing** when path points to file:
-   - Displays single image with prev/next navigation
-   - Finds sibling images in same directory
-   - Links to full-resolution image
+    - Displays single image with prev/next navigation

+
+The image view logic now lives in `viewer/image.py` and exposes additional context keys used by templates and tests (see `viewer/test.py`): `prev_url`, `next_url`, `prev_thumb`, `next_thumb`, `back_url`, `back_thumb`, `home_url`, `home_thumb`, and `image_meta` (filename/width/height/filesize/created/modified).
 
 ### Thumbnail Generation
 
 **Lazy generation approach** (viewer/utils.py):
 - Thumbnails created on-demand when viewing gallery
-- 128×128 pixel size (hardcoded)
+ - 128×128 pixel size (`THUMB_SIZE`) and cached under `THUMBNAILS_ROOT`
 - Uses Pillow for image processing
 - Fast extension-based image detection (no MIME-type I/O)
