[Plugin: NextGEN Gallery] Using it as simple banner/header

I’m very impressed by the features of this plugin, but for my project, I’m just looking for a simple slideshow banner with a couple of images for each page differently (as some sort of header) (so I need to create a couple of galleries I suppose, for each page a different one)

Though, I don’t want to embed this in my ‘post’ or ‘page’ but in my php code itself. How can I do this? I only see the option to include in a page or post..
