I would love a bit more complex version of this, which doesn't only affect the install button.
I'm looking for some kind of command that allows me to have a different image per style. That would mean I could write something like this: [img=blue]http://www.x.com/imageblue.gif[/img ]
[img=green1]http://www.x.com/imagegreen1.gif[/img ]
and that would allow me to show a different image per style, so that it fits in with all the backgrounds.
OK, it might be a bit selfisch, but has anyone actually looked at the image in my signature with the dark blue style?!?!
