Query: "How to use Photoshop to control Web Page Layout"

Very good on details of implementing the layout you already designed, but NOT the book you want on site design principles. For navigation principles, see the Polar Bear Book (O'Reilly's Web Navigation). Some good visual design principles are in Lynch and Horton's Web Style Guide. I'm still looking for the perfect ergonomic UI book for application design.
