Modifiera så att script använder ftp vid uppladdning

Jag har ett script som hjälper mig croppa bildfiler, 12CropImageinc.php:

Synd att man inte kan se rader i [ php ]-taggen, men på rad 164 (nästan längst ner) så hittar man dessa rader:

// now save the thumbnail 
             touch("../thumbnails/thumb_$file"); 
            imagejpeg($tmp_img, "../thumbnails/thumb_$file",$cfgrow['compression']); 
               $thumbimage = "../thumbnails/thumb_$file"; 
               chmod($thumbimage,0644); 
                imagedestroy($tmp_img); 
           return true;

Vad jag skulle behöva hjälp med är att göra så att det här scriptet använder FTP för att lägga upp filerna i stället för... vad den nu använder.

Är detta möjligt? Skulle vara otroligt jättetacksam för hjälp! :bire
