block-random.php: no such file or directory

Any ideas here?

I have downloaded block-random.php and installed in the gallery directory.

Here is the link:
http://www.mayhemstreetriders.com/random_test.php

Here is the code:
<?php
include("http://xtremehabits.com/phpBB2/modules.php?op=modload&name=gallery&file=index&include=block-random.php");
?>

Error:
Warning: main(modules/gallery/block-random.php) [function.main]: failed to create stream: No such file or directory in /usr/home/sites/www.xtremehabits.com/web/phpBB2/modules/gallery/index.php on line 115
