You can also directly insert it into the post by highlighting the link and then clicking the img button. In this case you should probably rezize it though, because it is too big to fit on the screen, so that you can only see part of it and then have to scroll.
Edit: Oops, Volker has said that already.
I have merged the two topics. Do you want this to become your art thread or shall I delete it later and you make a new one? I would like to keep the forum free from "test topics" as far as possible.
