If I run different instances of the same game, or I alternate between several images for the game's main page, I end up with duplicates of the images cluttering my library. These have the same file name and size (because I can't re-use the ones already in the library on the game page) and are "true" duplicates. Please provide an option to eliminate all but one copy (or make removing all an option) and connect any references to the surviving instance of the image.
