This is a short video I made for a friend to show off how easy it is to use PhotoShop 7.0 to build a website. This should be alright to use in CS2 or CS3. If you ask me, I'd definitely avoid doing this for larger pieces of one color (which should be tiled x or y in CSS). The advantage of using slices for your site is the website will look just how you intended. The drawback is having massive strain on your server from loading all those images over and over, not to mention the load times!
