{
 copy($old_path, $new_path);
} // if
{
if($height/(($ratio = $old_size[0]/$width)) >= $width)
{
$ratio = $old_size[1]/$height;
}   // if
$new_width = $old_size[0]/$ratio;
$new_height = $old_size[1]/$ratio;
$old_img = imagecreatefromstring(implode('', file($old_path)));
$new_img = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($new_img, $old_img, 0, 0, 0, 0, $new_width, $new_height, $old_size[0], $old_size[1]);
imagejpeg($new_img, $new_path);
