Ok, there is this site, http://msig.info/web2.php and it makes site logos and when you make one (type in something in the field and press generate) there is a popup that shows you this stuff, and I want to know how to do that, I know it is in AJAX and PHP, I just need to know how to do it, thanks for the help!!

You'll probably be using PHP's image functions: http://us3.php.net/gd

Best of luck; it's not easy.
