i have code like this:
(note folder.gif is 20w by 22h)
<?php
$source =  @imagecreatefromgif ("/home/sites/dazweb.co.uk/web/images/folder.gif");
$dest = imagecreate(100, 100);
$desti =  imagecopyresized ($dest, $source, 0, 0, 0, 0, 100, 100, 20, 22);
$a = imagegif($desti, "/home/sites/dazweb.co.uk/web/images/upload/test2.gif");
?>

the script will produce an exact copy of the source image not resized at all (changing the 100,100,10,12 to any numbers makes no difference at all) 
the users on the mailing list dont know how to solve it and some have had similar problems.

unfortunately the server is not mine so i cant give details on moduales etc..
