Ahhhhh ok. I took a look at the overlib script and there is no documentation on doing it for an image that inside the link you are running the mouse over on. So its most likely this was something that a developer coded for this site then. To the OP you may have to pay for this because modifying a JavaScript and making it work in vBulletin may be a stretch for someone just to spend tons of time and then post the code.
