    I have a PHP file that creates a watermark on ALL images in a specified folder.

    How can I modify this so that it only creates watermarks on images whos filenames start with a number but not with images whos filenames start with a letter?

    Put something like this under: 
     $filename=str_replace($dr, './', $_SERVER['PATH_INFO']);
    PHP:
    if (!in_array(substr($filename, 0, 1), range(0, 9))){
   readfile($filename);
   exit;
}
    PHP:
    Anything that doesn't begin with a number won't be processed.

    replace
    if (!in_array(substr($filename, 0, 1), range(0, 9))){ readfile($filename); exit;}

    with (if you want it to stop)
    if (!preg_match(/([\d]+)[\S]+$/iU",$filename,$match)) { exit;}
