Open social app.

I am looking to create a simple app for my site. For the end result the app will display pictures/logos in a container to be placed in my members profile. I want to create a folder that will hold all of these pictures. Even when I add new pictures they will be available updated in the app. Whom ever? uses this app on their profile, will be able to look at the 12 photos I have and be able to choose 6 or less photos from? canvas view. The 6 or less photos they have chosen will be displayed in their Profile view, for all to see.? Who can? handle this?
