Signature Addon Recommandations

I'm trying to find a pluggin that adds an image for users to place as there signature. Problem is that no matter the one i use i seem to be coming up empty on results with no image or text displayed, i know i'm missing some key element to this what seems simple addon to user post and comments.

Whether its to add a logo or banner by link for from a site that generates changing stats, to me it should not be this difficult.

Thanks for the Assist
