[Plugin: NextGEN Gallery] [How To] Gallery opens in a new page, full width, shows only thumbs in pos

I saw this website “bgr.com” using nextgen gallery in its posts [example go here]

How do I do exactly that? clicking on any image takes me to a completely new page without sidebars etc [like here]

Any help is deeply appreciated. Thanks.
