I would like to create a new button set, some will be standard graphic buttons (Add To Cart, Write Review, etc.) and some will be CSS Menu Rollovers, replacing links such as Home, Log In, New products, Specials, etc.

What do I need to edit to replace button images with my own images?

In Layout Settings. what does it mean if you select Images vs. CSS buttons? I can't see a difference when I switch.

Where can I get more detailed instructions for using EZ Pages and getting my menus and links wherever i want them?
