Image Gallery..

Aloha all.. Just wondering if anyone can help me with an issue I have.. I have tried to install a couple of image gallery plug ins, but when I do, it changes everything.. I am after something I can use only on certain pages.. I want my main posts to not be affected and stay the way it is, but i want to be able to have a gallery on other pages which will show all the images for that page in small images and then the one big image up top.. It’s for screen shots of an old TV show.. Thanx..
