On Unix systems, the xv program is very useful for creating imagemaps. Simply clicking on the image of the map displayed by xv gives the coordinates of the mouse pointer within the image as required by imagemap. However, there are now a few graphical tools available to help you do this.
An graphical editor called mapedit (see figure 8.1) has been released for Unix systems, which allows interactive graphical editing of imagemap and htimage configuration files. A similar program called webmap is also available for Apple Macintoshes.
