If the images originated from a recent digital camera, a thumbnail 
image might be stored in the original image. Take a look at the 
exig_thumbnail() function <http://www.php.net/exit_thumbnail>.

If that is not the case, there are image resampling functions in the 
GD package. Take a look at the imagecopyresampled() function 
<http://www.php.net/imagecopyresampled>.
