    if ($user){
        //fql query example using legacy method call and passing parameter
        try{
            $fql            =   "select name, hometown_location, sex, pic_square from user where uid=" . $user;

            //http://developers.facebook.com/docs/reference/fql/
            $param  =   array(
                'method'    => 'fql.query',
                'query'     => $fql,
                'callback'  => ''
            );
            $fqlResult   =   $facebook->api($param);
        }
        catch(Exception $o){
            d($o);
        }
    }
    //set page to include default is home.php
    $page   =   isset($_REQUEST['page']) ? $_REQUEST['page'] : "home.php";
    include_once "template.php";
?>

<?php
echo '<div id="namaz_content">';
echo '</div>';
echo $userInfo['picture'];
//Get the current users id
$uid = $facebook->getUser();

//create the url
$profile_pic =  "http://graph.facebook.com/".$uid."/picture?width=80&height=80";
//echo the image out
echo "<img src=\"" . $profile_pic . "\" />";

echo '<img src="image.php?name=My name is Tushar&result=A%2D&taka=1000&subject=math" />';

  // Allocate A Color For The Text


   $red = imagecolorallocate($dest,255,0,0);
   $blue= imagecolorallocate($dest,0,0,255);

  // Set Path to Font File
  $font_path = 'bdquiz.ttf';

  // Set Text to Be Printed On Image

  // Print Text On Image
    imagettftext($dest, 20, 0, 192, 240, $red, $font_path, $text);
    imagettftext($dest,35, 0, 72, 380, $red, 'arial.ttf', $result);
    imagettftext($dest,15, 0, 318, 420, $red, 'arial.ttf', $taka);
    imagettftext($dest,15, 0, 270, 348, $blue, 'arial.ttf', $subject);
imagecopymerge($dest, $src, 468, 186, 0, 0, 80, 80, 100); //have to play with these numbers for it to work for you, etc.

    //header('Content-Type: image/png');
    imagejpeg($dest);
    imagedestroy($dest);
    imagedestroy($src);
?>

I don't think you can do that with the code you provided above.

You might need to create a few more line code to adjust with the one above.

You need create a line to POST a new image meaning replace the it jpg to a new jpg.
