Drupal 7: Adding a save button to save content to user profile page I want a signed-in user to have the ability to save an image (that is being displayed in some kind of slideshow or gallery) and have it appear on that users profile page. So the image will be on the same site, maybe added by another user or the site admin and then any other user would be able to click a save button and have it added to their own profile. That image being saved (when being saved to the users profile) should have a link that returns you to the gallery from which you saved it.

How to do this?
For something really simple, you can use the Favorites module where users can add nodes to a "favorites" list. This is based off of the URL though, so a gallery of images rotating on one page wouldn't really work.

For a more robust system, you can configure a bunch of Flags, which can do many different things like bookmarks, favorites, etc.
