Feat: Backend Implementation for Image deletion

[JaYRaNa213]

Describe the feature

Continuation of #802 – Add Context Menu (Right-Click) Actions for Images

Backend:

• Has no API to delete images
• Does not remove files from disk
• Does not clean up database records or thumbnails
• This results in an incomplete and misleading UX.

Problem

There is no end-to-end flow for deleting an image:

• No backend endpoint for deletion
• No filesystem cleanup
• No database cleanup
• Frontend delete button not wired to any API
• Deleted images can reappear after refresh or restart

Goal

1. Implement complete image deletion support, including:
2. Backend API to delete images safely
3. Frontend wiring to trigger deletion
4. Proper cleanup of files, thumbnails, and database records
5. Gallery refresh after deletion

Expected Behavior

When a user clicks Delete Image from the context menu:
Frontend sends delete request to backend

Backend:

1. Deletes image file from disk
2. Deletes thumbnail / cached files
3. Removes image record from database
4. Frontend updates gallery state immediately

Proper error handling if:

File is missing
File is locked
DB record does not exist

Scope

Backend (Primary)

Files to Update / Create

Backend (Python)

Update

backend/app/routes/images.py

backend/app/database/images.py

backend/app/utils/images.py (if helper required)


// Add (if needed)

backend/app/schemas/delete_image.py

Frontend (Minimal Changes)

Update

• Context menu delete handler (existing UI)
• Gallery state refresh logic
• API Proposal

Preferred REST-style endpoint:

DELETE /images/{image_id}

Alternative (if path-based deletion is required):

POST /images/delete
Body: { image_id | image_path }

Acceptance Criteria ( Important)

• Image file is removed from disk
• Thumbnail/cached files are removed
• Database record is deleted
• Image does not reappear after refresh/restart
• UI updates instantly after deletion
• Safe error handling
