+# Done: Image Scaling & Gallery Upload UX (F-3)
+
+## Overview
+Unified image scaling for camera captures and gallery uploads (max 1280px), moved gallery upload from camera to gallery screen, added scroll position preservation.
+
+## Key Components
+- **Image scaling utility** (`scaleImageFile()`) - scales/compresses uploaded images to match camera captures
+- **Gallery upload relocation** - moved from CameraScreen to GalleryScreen
+- **Scroll position preservation** - maintains scroll state when returning to gallery
+- **E2E test coverage** - comprehensive image upload tests
+
+## Implementation Details
+
+### Files Changed
+- `src/utils/camera.ts` (+82 lines) - Added `scaleImageFile()` with validation, scaling, compression
+- `src/components/CameraScreen.tsx` (-88 lines) - Removed gallery upload button/logic
+- `src/components/GalleryScreen.tsx` (refactored) - Added gallery upload FAB, scroll position preservation
+- `src/components/DetailsScreen.tsx` (1 line) - Updated to use `scaleImageFile()`
+- `src/App.tsx` (+3 lines) - State updates for gallery upload flow
+- `e2e/image-upload.spec.ts` (+167 lines) - New test file for upload scenarios
+- `e2e/utils/page-objects.ts` (+8 lines) - Added gallery upload helper
+- `CLAUDE.md` (+19 lines) - Added testing requirements section
+
+### Technical Details
+- **Scaling logic**: Max 1280px, preserves aspect ratio, JPEG quality 0.7 (large) / 0.8 (small)
+- **Validation**: 10MB file size limit, image type check
+- **Performance**: URL.createObjectURL with proper cleanup
+- **Scroll preservation**: Saves/restores `scrollTop` on gallery navigation
+
+## User Benefits
+- **Consistent storage**: Gallery uploads now same size as camera captures (~200-400KB)
+- **Better UX**: Gallery button on gallery screen (more intuitive)
+- **Scroll preservation**: Returns to same position after viewing exposure details
+- **Better performance**: Smaller images load faster, especially on mobile
+
+## Testing Coverage
+- Gallery upload (camera screen removed, gallery screen working)
+- Image scaling verification (high-res images downscaled to 1280px)
+- Details screen image replacement
+- Scroll position preservation after navigation
+- File validation (size, type, invalid files)
