Summary
This hour explained how to create imagemaps—links that lead to more than one place, depending on where you click an image—as well as why and how to avoid using them whenever possible. You saw how to define rectangular and circular link regions within an image, as well as irregularly shaped polygonal regions. You also learned to provide an alternate link for people using older browsers that don't support the current imagemap standard. Finally, you got a quick run-down on providing server-side imagemaps on most types of Web servers—just in case you want to provide the best possible experience for users of outdated browsers.
Table 14.1 is a summary of the tags and attributes covered in this hour.
