[img] in Signature

[Xenos]

I'm unsure if this has been reported or not, but on my forum, it's not accepting the [img] tags in my signature... it's just putting it back in plain text--at least in the preview.

I have the setting for [img] tags in signatures on, so it must not like it for some reason. I want to be able to put a graphic in my signature, but it is not letting me.
