Thanks, Raze - I know that one can find out the link as long as the image is displayed. Unfortunately, my image wasn't displayed any longer. It has happened time and again that my avatar image vanished, e.g. because the avatar page where I had taken it from was restructured. In the old forum, the link was displayed even when the image was gone, so I at least knew where I could start looking for the image. In the new forum, this currently isn't possible.
The Larian stock avatars aren't bad (and one can't lose them, I know), but they look quite old-fashioned compared to the ones on the page I have linked above. Most of them have been taken from

, I guess ... I wouldn't mind having some nice rogue avatar from

, though

Unfortunately, half of the links in "Choose your avatar and Forum Classes" don't lead to avatar pages anymore: The first one links to a forum now, the second one's server isn't available anymore.
Switching to the new forum would have been a good opportunity for allowing larger avatars than 80 x 80 pixels. When I went looking for a new avatar image, I noticed that most pages don't even offer avatars that are so small ...
I do understand that there was a 80 x 80 pixels limit some years ago when people still used 56k modems and the loading times for larger avatars were annoying. But on a 22' monitor with 1680 x 1050 pixels resolution (which isn't that extravagant), those small avatars look rather, uhm, unimpressive

And to be honest, I can't understand the logic in limiting avatars to 80 x 80 pixels when at the same time, people are allowed to use signature images that are much, much larger.
