How to get full screen galleries in Marquee

I'm wondering if anyone knows how to get a full screen gallery using the Marquee template where the images extend under the transparent nav bar rather than below it.

One of the sample sites for the template has it, but I can't figure it out!

Here is the sample: http://todd-richardson.com/manhattan-photographs/0zfls8f0gcl0hnkbr0qjvcu85gn5f9

Thanks in advance!
