+title: Cache Art Crops
+status: Completed
+---
+
+## Objectives
+- Ensure "Art Crop" images are cached locally alongside "Normal" images to support offline mode and reduce external API calls.
+- Update `CardService` (Server) to download and save `.crop.jpg` files.
+- Update `PackGeneratorService` (Client) to use local `.crop.jpg` URLs when `useLocalImages` is enabled.
+
+## Implementation Details
+1.  **Server (`CardService.ts`)**:
+    - Modified `cacheImages` loop to detect if `image_uris.art_crop` (or face equivalent) exists.
+    - Implemented concurrent downloading of both the normal image and the art crop.
+    - Saves art crops with the pattern: `public/cards/images/[setCode]/[uuid].crop.jpg`.
+
+2.  **Client (`PackGeneratorService.ts`)**:
+    - Updated `processCards` to check the `useLocalImages` flag.
+    - If true, constructs the `imageArtCrop` URL using the local server path: `${origin}/cards/images/${set}/${id}.crop.jpg`.
+
+## Impact
+- When users import a cube or set collection, both image versions will now be stored.
+- The Battlefield view (which uses `art_crop`) will now load instantly from the local server cache instead of Scryfall.
