[Plugin: NextGEN Scroll Gallery] Integration w/ lightbox

I’m having trouble with lightbox integration for scrollGallery… I’d like my site to function similarly to the example given at the the scrollGallery homepage, i.e. thumbnails only, and lightbox on click. Can somebody go into greater detail on this topic?
