Gleam gallery page template

I’m still fairly new to working with themes here on wordpress, but I’m using the gleam theme for elegangthemes and it’s working okay so far. However, I would like to make a gallery page like the one on the their website, but I can’t seem to figure out how to make that happen. There is a page template, which is called gallery page, but it doesn’t really have a lot of options to configure. Do any of you guys have some experience with this theme?
