If you click the link straight from this web site, you get a vDeck error:
403 forbidden
Server configuration does not allow access to this page
Click the "go" button again, and the image comes up.
when you first come into this thread, you can breifly see the image appear, and this disappear....so you've either got some permissions screwed up on your images folder (permissions should be SCHMOD 644) or you've got anti-hotlinking software on your server...
