i think what you're referring to is the carousel gallery. naay daghan ani using jquery. you can search the net for code snippets.
but as for the site, i think this is the script that makes the slider fade in and out.
Code:
<script type="text/javascript">
//<![CDATA[
window.addEvent('domready', function(){
var data = {'interface/img/slideshow/tournament.png': { caption: '$2000 - Beta Tournament', href: 'http://clgaming.net/board/board25-announcements/board26-community-news/4513-2000-beta-tournamentception/' },'interface/img/slideshow/guides.png': { caption: 'CLG Guides', href: 'http://clgaming.net/guides' },'interface/img/slideshow/razer.jpg': { caption: 'Counter Logic Gaming tie the knot with Razer', href: 'http://clgaming.net/board/board25-announcements/board2-news/2425-counter-logic-gaming-tie-the-knot-with-razer/' },'interface/img/slideshow/reignofgaming.jpg': { caption: 'Reign of Gaming', href: 'http://rog.clgaming.net/' },
};
var myShow = new Slideshow('slideshow', data, { captions: true, controller: false, height: 250, width: 768, delay: 8000, thumbnails: true, replace: '' });
});
//]]>
</script>
it has an array that has the image urls, the caption and the link.
