While working with InspireBook I have noticed that the Album Covers (Cover photos, Profile images, etc) show the last uploaded photo as the Album Cover regardless if it was uploaded by that user or not. This happens when you use the “Edit Profile Picture” and “Change Cover” hover-over menus.
The albums show correctly if you access them directly through the albums tab.
For example: in your demo I currently see user "vrushankpb"s recently uploaded picture as my cover photo album. This will be confusing to users and could also be exploited by users to advertise or for mischief displaying an obscene image to all users.
