David, thanks - I'd noticed that Save for Web offered HTML as a file format, and had also noticed Slice - but hadn't taken time to read about or try it. I still haven't learned to work with ImageReady as much as I want, and now I know that I'll learn how to handle slices in PShop also.
Garfield, if you're using a recent version of PShop, it includes ImageReady also, so you can try both methods. There are all kinds of tutorials
Tutorial - ImageReady - just use Google to look up "Photoshop Imageready slice" or some other combination.
