When I went about this I created a custom file upload form block that placed all user uploads in a specific set. Something like "User Uploads".

Then I created a block that only showed that particular "User Uploads" set and then filtered that list by the image file owner.

Then I created a block that allowed users to delete images they no longer wanted.

The nice thing about this method is that your site admin can still use the file manager to moderate the user uploads and you don't have to deal with any database tables.

The bad this is all the code you have to write. Sorry I don't have any to share. It was a while ago, and I don't remember it being super pretty.

Thank you.
Yeah I'm still looking to see a way to do this. but it's a mess. the whole profile page thing is somewhat silly.
