I prefer to use imagemagick, has more features and you can use seam
carving if you make some dimension changes when you scale down your image.

Good example on what you can do with imagemagick can be found at
valokuva.org (Mikko's blog, the guy who maintains the imagemagick
extension for PHP).

A seam carving example: http://valokuva.org/?m=200802

If you want it to be saved to a file instead, then remove the

/* Display */
header( 'Content-Type: image/jpg' );
echo $im;

and replace it with

/* Save to file */
$im->writeImage('test.png');
$im->clear();
$im->destroy();
