hi i have a problem creating captcha system. i create some basic script for image displaying but it says this error
Code: The image “http://localhost/examples/captcha.php” cannot be displayed, because it contains errors.
my code is here

Code: <?php
$img = imagecreatetruecolor(80,30);

$white = imagecolorallocate($img, 255, 255, 255);
$black = imagecolorallocate($img, 0, 0, 0);
$red = imagecolorallocate($img, 255, 0, 0);
$pink = imagecolorallocate($img, 200, 0, 150);

imagefill($img, 0, 0, $black);

imagettftext($img, 12, 0, 15, 15, "calibri.ttf", "hello");

header("Content-type: image/png");
imagepng($img);
imagedestroy($img);
?>
where is the error and how it can be fixed?
