You have to cycle the background animation somehow.I wouldn't try it with a single photo. Instead I would try to tile it so the same chunk can repeatedly appear from behind periodically and keep shrinking as the camera moves away.
This probably isn't proper technique, as it came from the top of my head as I was typing something completely different :^P
