Quick Reference

A file that is stored on a Web server and is associated with an image map that occurs on a Web page which is maintained by the server. The file contains details of the shape of entities on the image map: whether, for example, they are circles or rectangles, the dimensions of the entity, and the URL associated with the entity to which control is transferred when it is clicked in a browser window. There are two formats for such files: the CERN image map format and the NCSA Image Map Format. They are structurally similar, the only difference between them being the format of the data they contain. Creating such files manually is very tedious; they are normally created by specialized tools which, for example, allow you to draw image map regions over existing graphics.
