+# Phase 5 Plan 2: Provider Image Integration Summary
+
+**img2img support for Replicate and fal.ai via automatic image URL conversion with cleanup**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-09T09:51:03Z
+- **Completed:** 2026-01-09T09:53:44Z
+- **Tasks:** 3
+- **Files modified:** 1
+
+## Accomplishments
+
+- Replicate predictions receive image input via `image` parameter
+- fal.ai requests receive image input via `image_url` parameter
+- Large images (>256KB) automatically converted to temporary URLs
+- Uploaded images cleaned up immediately after provider call completes
+- Small images pass efficiently as data URIs
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update generateWithReplicate to pass image input** - `4477f6f` (feat)
+2. **Task 2: Update generateWithFal to pass image_url parameter** - `6324af3` (feat)
+3. **Task 3: Upload images to URL server with cleanup** - `2195a6e` (feat)
+
+**Plan metadata:** (pending)
+
+## Files Created/Modified
+
+- `src/app/api/generate/route.ts` - Added image parameter passing and URL conversion logic
+
+## Decisions Made
+
+- Use `image` parameter for Replicate (most common for img2img models, future enhancement could detect from model schema)
+- Use `image_url` parameter for fal.ai (consistent across all fal.ai models)
+- Small images use data URIs directly for efficiency
+- Gemini path unchanged (it handles base64 directly without URL conversion)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Next Phase Readiness
+
+- Phase 5 complete: Image URL server infrastructure fully integrated
+- Ready for Phase 6: Video & Polish
