Creating a photo

I need some help creating a photo gallery for my site however the gallery on this site really isnt what I am looking for. What I am looking for is when you click a link on my page (i.e. music) it loads a smaller seperate window with thumbnails on the left and a space for the image on the right. When you move the mouse over a thumbnail I wanted it to change color and load the image on the right. A good example is If you can help I would appreciate it. The way I had it in the past was very clunky. You clicked on an image and it loaded a seperate page (same window) with next and back buttons. Thanks for everything!
