Then why didn't you say ;). There's lots of inforation available about this online, search on google for things like 'PHP Thumbnailing', and you'll find lots of scripts to do it for you.

check out http://us2.php.net/manual/en/ref.image.php with reference to these functions. You're going to have to read the source image's size with something like getimagesize() and then use the ratio of those dimensions to create your new dimensions.
