Creating An Online Photo Album

Hi,
I'm learning the PHP, and I've test this tutorial. It's very good.
But I want to change a little this script.
For the thumbnails, there is this in gallerysizer.php:

DEFINE("RESIZE_WIDTH", 400);
DEFINE("RESIZE_HEIGHT", 300);

But I want to resize with the % of the widht.
Examples,
the picture is in 800 * 600
I want a thumbnail at 400*300 (So 50% of 800) and I want to the script count the proportion of the height.
SO, if I hava a pictu who are in 800*540, the script count, 400 for the height, and 50% of 540 for the width.

How I can DO?
Thank you very much
