[Feature] Show owner of picture in shared album

I have searched the existing feature requests to make sure this is not a duplicate request.

• Yes

The feature

When several people upload their pictures to a shared album, it would be nice to see who's the original author/owner of the picture.
It could be either:
• In the "info" section of the picture
• A small watermark at the bottom right of the picture (maybe on mouseover)

Platform

• Server
• Web
• Mobile
