resizing an image with the gd library

I'm trying to resize an image with the gd library and am having some
difficulty. Here's my code:


$img = 'http://upload.wikimedia.org/wikipedia/commons/e/e3/Kheops-
Pyramid.jpg';
list($width, $height) = getimagesize($img);
$img = imagecreatefromjpeg($img);

$temp = imagecreate(500, 500);
imagecopyresized($img, $temp, 0, 0, 0, 0, 500, 500, $width, $height);

header('Content-type: image/jpeg');
imagejpeg($temp);
?>

All I get is a 500x500 black picture. What I don't get is a resized
wikimedia.org picture. Any ideas as to what I'm doing wrong?

That was it - thanks!
