Woah.. that way to much math for my brain at the moment :) If I understand the situation properly you need to take a smaller image and make it the boundary for the larger image?? I might suggest looking at imagick, it is a bit more friendlier with image manipulation: http://pecl.php.net/package/imagick Curt -- First, let me assure you that this is not one of those shady pyramid schemes you've been hearing about.
