php slackware package has gd enabled,
why don't you just install the package ?

Also to try it :
image.php
PHP Code:
<?php
$im 
= @imagecreate(100,100)
   or die(
'Cannot Initialize new GD image stream');
$background_color imagecolorallocate($im2389999);

$white imagecolorallocate($im255255255);
imagestring($im2515'GD enabled',$white);
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>

Most likely you're not sending the right content-type header. Could you post the script in question so somebody can check it out? Or try it on a known-working server.

FWIW, a good 25% of the content on my webpage is dynamically generated graphical content by PHP. I compiled my own PHP, but I used the pre-compiled GD library for it. I'm using GD extensively, most obviously in the gallery which generates thumbnails on the fly and is able to resize pictures dynamically from the original source.

Also to debug the script try to comment this line :
header('Content-type: image/png');

So any error message will be displayed or
use command : tail /var/log/apache/error_log

The first line of your file should be the <?php line.
Do not put any whitespace before it...

I tried the same, and I had an empty line before the supplied code. This makes php think it has to output html code... I got exactly the same error as you did. After removing the empty line it works.
