Forum:Image appear in tooltip

Hey, I've been trying to make tooltips containing an image appear when a cursor hovers over a link. I've tried the method both here and here.

My wiki is now littered with code that isn't working, and is proving no use. I'm at a bit of a loss. Can someone help me out .. please?:)
