Images in signature don't work

[Brim]

Hello everyone.
Like a lot of other people I have the problem that the images in the signature don't show up. I tried to find a solution in the existing threads but I fear I did not quite understood what I have to do. :/
(I did not do any modifications besides editing the template so far)
Anyone able to help me? Thanks in advance!

EDIT: btw: the image shows up when I enter the url alone! But never the less the url isn't accepted in any forum. So as a stand alone window it works but in a forum not. Any idea how this can be?
The forum I tested it is a wbblite 1.0.2

EDIT2: ok...to solve this I played around a little and what I found is really confusing: seems the code works on some forums (this for example) but not on others.
I think the best solution to get it working in other forums as well would be to have a link directly to the picture (ending with .gif) instead of the siggy.php id thing. Anybody knows a way to mod it this way so that the diplayed image is still fitting (and changing with chnages in levels)?

Oh that's an easy one. Stick this whereever you have the BBCode page.

$image = getcurrentimage($aid);
article_content = article_content."
<textarea name='textarea' cols='50' rows='4'>[img]".$image."[/img]
</textarea>";

That goes and gets the actual image being used. However the only problem with this version is it will not go and get the new image if the adoptable is leveled up.
