I have reasearched this a bit but it does not work Crying or Very sad

Code:
<?php

header("Content-type: image/gif");
$string = $_GET['text'];
$im    = imagecreatefrompng("http://www.dougie.frih.net/images/files.gif");
$orange = imagecolorallocate($im, 220, 210, 60);
$px    = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);

?>

Why does it not work and please don't just say, "That is Easy." Laughing

I've taken the liberty to paste your code unquoted and out of code block so that the reds can be seen

<?php

header("Content-type: image/gif"); ### A
$string = $_GET['text'];
$im = imagecreatefrompng("http://www.dougie.frih.net/images/files.gif"); ### B
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im); ### C
imagedestroy($im);

?>

The first line says you're about to output a gif image ... but you end up outputting a png image (lines A and C).
You're also trying to read a gif image as if it was a png (line B).

Thanks very much. lol. That was a school boy error!

One more thing ...

You read the template image from the webserver
Code:
$im = imagecreatefrompng("http://www.dougie.frih.net/images/files.gif");

I very much prefer to read it directly from the file system
Code:
$im = imagecreatefrompng('/home/dougie/domains/dougie.frih.net/images/files.gif');
