The feature
In shared albums, multiple users often upload the same or very similar photos, which leads to clutter and makes it hard to browse through the album efficiently. I propose implementing a duplicate photo detection system specifically for shared albums.

This system should:

Automatically Identify Duplicates: Use image recognition or hash-based comparison to detect identical or near-identical photos uploaded by different users in a shared album.
Provide Management Options: Once duplicates are detected, offer options such as:
Automatically flagging duplicates for review by album owners/administrators.
Allowing album owners/administrators to bulk delete duplicate photos from the shared album (without deleting the original from the uploader's personal library).
Giving a choice to remove a photo from the shared album while keeping it in the uploader's own collection.
Notification and Collaboration: Notify the relevant users (uploaders of duplicate photos) about the detection, so they can collaborate on deciding which version to keep in the shared album.
