Just trapped on a little tool to slice website images.
Quick in preparing ready html from simple single-image site design.
Program is rather crappy and cheap (especially comparing to similar function in PhotoShop).
But! Just look what books come as a bonus:
Search Engine Optimization: An Hour a Day
Web Design in a Nutshell, 3rd Edition
Webmaster in a Nutshell, 3rd Edition
I wonder how $270 priced books can be sold for just 20 dollars...
Anyway here's link: http://www.sliceimage.com/
Hope these books will help you as well.
