It does indeed allow you to create 'active' graphics that can go straight into web pages. So you can create a button bar with rollover buttons, each of which is a link to a page. In Fireworks, you 'slice' the image into the buttons, and use layers and frames to define the rollovers. After that, you define the link targets, and then export the graphic. The image is sliced into all its constituent parts, and the HTML is written.
Best part is, you save the whole lot as a PNG somewhere, and if you need to change anything, all your layers and definitions are still present, so you can edit the image really easily.
