       if (ereg ("^image/pjpeg",$photo_type)) {
        $img_e2=imagecreatefromjpeg($original_photo);
       }else if (ereg ("^image/gif",$photo_type)) {
        $img_e2=imagecreatefromgif($original_photo);
       }

2 คำสั่งนี้อาจผิดพลาด

type อาจ ไม่ได้อยู่ใน 2 ตัวนี้ ทำให้ $img_e2 ไม่ถูกต้อง

โค้ด resize image มีบนเว็บ ลองหาดู หรือไม่ก็ดูใน GCMS
