#7 Favorite pictures

[kjarri]

Give users the possibility of keeping track of their
favorite pictures in the photoalbum. User could, when
viewing a picture, click on link that would add the
current picture to his/her favorite pictures.

The user would then get a new category containing the
pictures he has added to his favorites.

This could then later be extended to let the user
create his own "virtual" categories where the user
could organize the picture as he wants.
