Highend WP theme simple gallery

Hi,
Your theme looks absolutely awesome, I only have one question: can you actually set-up a fairly “basic” gallery, i.e. 3-4 columns of thumbnails, each opening a single picture in a lightbox? The reason I am asking is that in your demo, clicking on a thumbnail under the portfolio gallery opens three pictures and I can’t see just a plain gallery (like this one http://hb-themes.com/themes/landscaper_wp/gallery/#!prettyPhoto).
Many thanks!
