photomag gallery question

hello, i'm new to all of this and im trying to figure out how to get the type of gallery im looking for. Perhaps somebody can offer me a suggestion for a good gallery plugin that is compatible with the photomag theme. What I'm looking for is a gallery that I can make a page that once someone opens it, in a way, transforms the entire page into a presentation. All the galleries that I'm finding, once they open they are nothing more than a drop down page. I want more of a presentation. I guess what im really looking for is when you open this page everything fades away, the header, the title, even possibly the menus.
Anyone have any suggestions? Please help?
