The Hotspot Tools allow you to create Rectangular, Circular, and Polygonal Image Maps for the graphics that you create. Fireworks will generate all of the requisite HTML code and save it with your graphic when you export it.

The Slice Tools allow you to cut your image up into slices and, if so desired, adjust the optimization settings for each slice. Fireworks will place the individual slices into an HTML table when you export your document and it will display in a browser exactly the way that you created it.
