Using a GD that has GIF support, you can do this....
<?php
// we expect $scale and $image to be defined, having been passed to us via
// query string, e.g. http://www.foo.com/img.php3?image=test.gif&scale=4
// create an image object from the source file
$srcImg = imagecreatefromgif($DOCUMENT_ROOT . $image);
// create a (blank) smaller image object
$srcSize = getimagesize($DOCUMENT_ROOT . $image);
$dstImg = imagecreate($srcSize[0]/$scale, $srcSize[1]/$scale);
// copy and resize from the source image object to the smaller blank one
imagecopyresized($dstImg, $srcImg, 0, 0, 0, 0,
$srcSize[0]/$scale, $srcSize[1]/$scale,
$srcSize[0], $srcSize[1]);
// send the smaller image object to the browser
header( "Content-Type: image/gif");
imagegif($dstImg);
// clean up
imagedestroy($scrImg);
imagedestroy($dstImg);
?>
