I have to report the same issue, both with the WIki and in the forums. All I get is a white box in place of graphics and that persists after refresh.
Both work just fine using the Web Interface outside of game, the problem in only when I access them in game.
I should perhaps add that I consistently get timeouts when using the whole Shift+W set of tools while in game, so my guess is that whatever that issue is carries into the ability to access pics. I've generally assumed it's the price I pay for being so far from the servers but if a fix exists that would be great.
