Image signature for admin only
 

I cannot find any hack that allow only Admin (or mods) to have an image in his signature.
I want to keep turned off the img tag for everyone, except admin and moderators.

Do someone knows how to do this or where I could find this hack?

Thank you for your help.

easiest way:
create a new bbcode for example [aimg] and use this.
as users can't view the source of sigs, they can't find out.
and if they do a mod told them....

Thank you very much !
