Relax, it can take up to a day or so for the proper image to propagate through the network. If you're really in a rush, you can always reboot your own machine to ensure it isn't on your end first, and then if it isn't, then you may need to find a good book.
Also, what is a single picture going to do to ruin your game, may I ask? Unless it was copyright infringing... But in that case, why would you even use it in the first place!?
Sometimes the best remedy to a situation like this one is to acquire the virtue of patience.
