Here's a first pass at a possible album collab app (platform unknown). The sidebar consists of the albums I have access to. The "Valio Con 2013" album is currently open/expanded and the forth photo in the left column is selected.
The pencil icon represents "edit" which, when clicked, switches out the mini album view with options like album name, notifications, who's involved, add member, remove, etc.
Right column is the currently opened photo. Bottom left shows who uploaded it, bottom right toggles the comments (both only visible on hover). App icon beneath :)
