Here is what I found on Amazon's website:

function createthumb($name,$filename,$new_w,$new_h){
      $system=explode('.',$name);
      if (preg_match('/jpg|jpeg/',$system[1])){
           $src_img=imagecreatefromjpeg($name);
      }
      if (preg_match('/png/',$system[1])){
           $src_img=imagecreatefrompng($name);
      }
      $old_x=imageSX($src_img);
      $old_y=imageSY($src_img);
      if ($old_x > $old_y) {
           $thumb_w=$new_w;
           $thumb_h=$old_y*($new_h/$old_x);
      }
      if ($old_x < $old_y) {
           $thumb_w=$old_x*($new_w/$old_y);
           $thumb_h=$new_h;
      }
      if ($old_x == $old_y) {
           $thumb_w=$new_w;
           $thumb_h=$new_h;
      }
      $dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
      imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
      if (preg_match("/png/",$system[1])){
           imagepng($dst_img,$filename); 
      } else {
           imagejpeg($dst_img,$filename); 
      }
      imagedestroy($dst_img); 
      imagedestroy($src_img); 
 }

The createthumb() function is a simple function that takes four arguments: file to process, output file name, width of output file, and height of output file. The function makes use of GD image-manipulation tools and is adapted from Christian Heilmann’s function available at http://icant.co.uk/articles/phpthumbnails/.

Here is another thumbnail library: http://phpthumb.sourceforge.net/
