cant get image from database

[Stobor]

Sorry for double posting , posted 1 thread in the wrong forum because its obviously more related to php than sql.
database "dota2"
table "images"
id(int11)
pics(blob)
ext(varchar4)
gender(varchar7)

now i have 1 image stored "id" 5 "pics" [BLOB - 1.4 KiB] "ext" jpg "gender" china
storing code

$con = mysql_connect("localhost","root","aa");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }


echo "Success! You have connected ";

$handle = fopen("ch.jpg", "rb");
$img = fread($handle, filesize('ch.jpg'));
fclose($handle);
if (!$img)
{echo"not working";}

$img = base64_encode($img);
 mysql_connect("localhost","root","aa") or die(mysql_error()); 
 mysql_select_db("dota2") or die(mysql_error()); 
$sql = "INSERT INTO images(id, pics, ext, gender) values (null,'$img','jpg','china')";
mysql_query($sql) or die('Bad Query at 12');
echo "Success! You have inserted your picture!"; 

showing code

header("Content-type: image/jpg");
$con = mysql_connect("localhost","root","aa") or die(mysql_error()); 
mysql_select_db("dota2");
$getImage = mysql_query("SELECT pics FROM images WHERE id = 5") or die(mysql_error());
$row_getImage = mysql_fetch_array($getImage, $con);

echo $row_getImage['pics'];
mysql_free_result($getImage); 

shows error " the image "http://localhost/test2/showimage.php" cannot be displayed ebcause it contains errors", any help ?
