Witam
Mam o to taki skrypt uploadu zdjęć na serwer. Skrypt ma wrzucić obrazek do katalogu 'photo/tmp' a następnie pomniejszony ten obrazek do folderu 'photo'.
Normalne zdjęcie do folderu 'photo/tmp' wrzuca poprawnie, lecz pomniejszony obrazek w folderze photo jest cały czarny.
Jak to poprawić

if(is_uploaded_file($_FILES['girl_photo']['tmp_name'])){
 
        $type=end(explode("/",$_FILES['girl_photo']['type']));
        $filename="photo/tmp/".$fileName.'.jpg';
        if(!move_uploaded_file($_FILES['girl_photo']['tmp_name'],$filename)){
            echo 'error';
	    }
 
        list($oldWidth, $oldHeight) = getimagesize($filename);
 
        $ratio=400/$oldWidth;
 
        $newWidth=400;
        $newHeight=$oldHeight*$ratio;
 
        $cutHeight=floor(($newHeight-400)/2);
 
        echo $newWidth.'<br>';
        echo $newHeight.'<br>';
        //exit();
 
 
        switch($type) {
            case 'jpeg':
              $org = imagecreatefromjpeg($filename);
              break;
            case 'gif':
              $org = imagecreatefromgif($filename);
              break;
            case 'png':
              $org = imagecreatefrompng($filename);
              break;
          }
 
 
        $image_p = imagecreatetruecolor($newWidth, $newHeight);
        $image = imagecreatefromjpeg($filename);
        imagecopyresampled($image_p, $image, 0, 0, 0, 0, $newWidth, $newGeight, $oldWidth, $oldHeight);
 
        $filename2="photo/".$fileName.'.jpg';
        imagejpeg($image_p, $filename2, 100);
