Notes on image mapping
You can make a map using Photoshop and its "slice" tool, which generates a folder full of pieces of image and an HTML "table" to hold them together. The "sliced" version of this map includes more than 30 images, many of them chunks of the blank white margins, and more than 260 lines of HTML code.
OR you can save one image, do no slicing, place it on a Web page and use Dreamweaver's image-map tool to identify the clickable regions.
It does the job in fewer than two-dozen lines of code.
