Automatic texture import in FINISHED game

Hi everyone,

I don’t know if it is even possible, but here’s what I want to do with Unreal:

I want to create a application/game, in which the user is able to look at some nice pictures, placed in a museum. But the user shall have the possibility to import his own images, so they replace the old pictures and can be watched in the museum. I know there’s an Auto-Import function for the editor, but has somebody any idea how to do this after the game has been packaged? Is this even posssible?

Any help is really appreciated!
