Right, I've been trying with GDLib for about 1/2 hour now without any luck...
So maybe one of you can assist me

Here's my gdtest.php code:

PHP Code:


<?php

header("Content-type: image/png");
$string ="If you can see this then I assume it's working?";
$im = imagecreatefrompng("button1.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);

?>

It outputs "The image “http://localhost/site/gdtest.php” cannot be displayed, because it contains errors."

"gd" part of my phpinfo page:

Any help would be greatly appreicated, and I'd rep you obv.

And add whatever font's you want.
