The default statement at the beginning just says that if the user clicks on anything else besides the specified coordinates, then it goes to this default HTML document, normally the home page of the user or to the original document page.

The above directions are generally what is needed to create an imagemap.
Most people only use rectangles.
The format of creation is still the same. You need an image.map file, your GIF, a GIF viewer that gives x,y coordinates, and your anchor. None of these change in format either except for the image.map file. Use the GIF viewer to find the coordinates needed as explained below, the anchor reference stays the same as above. To define an area the shape of a circle.
