Just try to remember that the cache system on Wikia's side takes a while to update. Sometimes even if you change an Achievement picture it doesn't change right away. It can actually take a few weeks for the cache to update.

Basically what I'm trying to say is that if an image doesn't change despite you constantly trying to change it, it might be because the cache system hasn't updated on Wikia's side.
