Plugin allows user to place favorite images to JomSocial profile.
You can select what images from all photos should be shown on the profile page for visitors.
If the plugin is installed on the site a user will be able to add it in his Applications>Browse. Admin can make this a core default application in the BE. Then a user won't have to add it.
Once added a user will be able to select featured images from the ones uploaded to his albums on his Profile tab. Then next time guests will see selected photos once they open the user's profile.
