使用curl检索图像 - php（issue）

Question

I need to retrieve image from database and store it to a folder. Once I used copy function with direct URL file-access to get the image from database..But it didn't work in our server. because allow_url_fopen is off in our server.. So now I am trying curl function to get the image..

This is my code

  $curl = curl_init("http://localhost/matrimony/admin/getImage.php?id=24");
  curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
  curl_setopt($curl, CURLOPT_HEADER, 0);
  if(($data = curl_exec($curl)) === false)
        echo "curl error";
  else{
    $im = imagecreatefromstring($data);
    if ($im !== false) {
        header('Content-Type: image/jpeg');
        imagejpeg($im);
        imagedestroy($im);
    }
    else {
        echo 'An error occurred.';
    }
    //return $data;
  }
  curl_close ($curl);

The result is

ÿØÿàJFIFÿþ>CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality ÿÛC    $.'

and my getImage code is

    $image = $_GET['id'];
    $rs = mysql_query("select ImgData from tblphotos where PhotoId=$image");
$n=mysql_num_rows($rs);
if($n>0)
{
    $row = mysql_fetch_assoc($rs);
    $imagebytes = $row['ImgData'];
    header("Content-type: image/jpeg");
    print $imagebytes;
}

Is there any mistakes in my code?. I don't know what I have to do..

php.net/manual/de/function.imagejpeg.php second parameter if you want to save it to a file (should be an answer and not a comment
