Did you ever click on a photo in facebook and wish you could zoom in and see a larger size (or even the original) in order to see more detail of a specific part? I sure have. The future where they maintain huge images is the future where enough people want to be able to do that and the cost of supporting it is small enough. It really isn't too hard to imagine.
