i am trying to create my own captcha on my page for log in but this php code won't display my captcha image on my web page. so any suggetion will be good. this is my captcha.php
<?php
session_start();
// generate random number and store in session
$randomnr = rand(1000, 9999);
$_SESSION['randomnr2'] = md5($randomnr);
//generate image
$im = imagecreatetruecolor(100, 38);
//colors:
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 200, 35, $black);
// ------------- your fontname -------------
// example font http://www.webpagepublicity.com/free-fonts/a/Anklepants.ttf
$font = 'Anklepants.ttf';
//draw text:
imagettftext($im, 35, 0, 22, 24, $grey, $font, $randomnr);
imagettftext($im, 35, 0, 15, 26, $white, $font, $randomnr);
// prevent client side caching
header("Expires: Wed, 1 Jan 2015 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revаlidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
//send image to browser
header ("Content-type: image/PNG");
imagegif($im);
imagedestroy($im);
?>
