Normally I would tell you to put the "a href" tag around the img tag that shows that image, but you're using a forum. I've never used versatileBulletinBoard, but there must be a setting in the admin panel where you can change this. Right now it appears to be:

http://www.hellsknights.southietech....p?target=forum

You probably have to change it from there to something else. I'm not familiar with that forum, so I can't really be of much help. Sorry.
