Photo slider/gallery to a page not a post

i was just wondering if anyone knew how to add a gallery to a page, not a post. As i have a few tabs on my blog site and one of them i wanted to be a gallery. But everywhere i look only suggests that i can do it on the main page, where all the posts go. Can anyone help me out? Or does blogger just not let you do that?
Any help is greatly appreciated
