I am looking for a script that will convert a gif picture to png format in realtime.

So that convert.php?picture.gif.jpg or whatever returns a png of the original image picture.gif.

I need it to work with PHP in a Linux enviroment. I have the Gallery NETPBM binaries installed and would like to use NETPBM if possible.

Any ideas?

Thanks,
Hank[/b]

Sure, here goes:

<?php
$netpbmPath = "/fill/this/in/with/the/netpbm/path"; //don't put a slash on the end

header ("Content-Type: image/png");

$file = $_SERVER['QUERY_STRING'];
echo `$netpbmPath/giftopnm $file | $netpbmPath/pnmtopng`;
?>

That should work. Post back if it doesn't.
