I just looked in both the Tutorials section (out on the main site) and the Tips Archive here and could see the pictures in both.
Are you able to see pictures here in the main forum? It might be something to do with your connection / browser.
For images within the forums I know you have to be logged in or you can't see them. Of course you have to be logged in to post so if you were able to leave this message you should have been able to see pictures as well....
