I've been reading these Visual Quick Start books for some time, and I am very impressed with this one.
The author lays out the book in a very orderly manner. She starts with the basics of the program and goes all the way to really advanced topics like swap-image behaviors. Very complicated, yet explained totally.
She also explains why I should do something. This is good for anyone who is just starting out on the web. (Most books on other programs just tell you what to do and don't explain why.)
The chapter on color was terrific. It explained a lot about what web-safe colors are and when to use dithering. And the chapter on optimizing clearly explained when to use GIF and when to use JPEG.
I really appreciated the chapters on working with objects. I knew a little about Photoshop, but I didn't understand Fireworks object tools. This book explained it all clearly. (In fact, I now feel a little more comfortable using Photoshop's Pen tool.)
Finally, I liked the fact that there were individual chapters for Optimizing, Exporting, Slicing, Rollovers, Animations, and Hotspots. They covered everything I needed to understand those topics.
Now that I've got this book, I feel much more comfortable creating graphics for my pages.
