Determining Your Coordinates
Imagemaps consist of two parts; the first is the image used for the imagemap. The second
is the set of HTML tags used to define the regions of the imagemap that serve as links.
To define these tags, you must determine the exact coordinates on your image that define
the regions you’ll use as links.
You can determine these coordinates either by sketching regions and manually noting
the coordinates or by using an imagemap creation program. The latter method is easier
because the program automatically generates a map file based on the regions you draw
with the mouse.
