By supplying PHP with the height & width, preferably as GET variables.
Then you can use the function imagecopyresampled to scale the image as
needed. See the examples at http://nl2.php.net/imagecopyresampled.

Just set the src of the image to be the php script, imagejpg/-png/-gif
will send the resized image back to the browser as long as you don't
specify a filename.
