A clickable image map is one that links to different places depending
on where you click on the image. The image is divided into
regions whose boundaries may or may not be visible.
For example, a map of the United States with state boundaries might
contain links to information about each state, and these links are
activated when you click within a state boundary.
In order to create a clickable image map you need to:
- Obtain the image you want in GIF or JPEG format and store it in
your
public_html directory or some sub-directory
therein
- Create lists of the coordinates, in pixel values,
that define each clickable region in the image
- Create the necessary HTML code to specify the image, the regions
in the image that you may click on, and the places (links)
that you are sent when you click on them.
There are at least three ways to create clickable image maps:
