Need help with a JS Slide Effect

Don’t know if there’s an available solution already available somewhere, but I was wondering if anyone might be able to help recreate the slide effect found here: http://www.lowepro.com/Products/Sling_Bags/. Clicking on the arrow icon to the right side of the screen produces a nice slide effect which looks to call up a new page.

I’m clueless when it comes to JS, so I guess I’m looking for some major help here.

Thanks.
