Are there server-side image map or client-side image maps?
An “image map” is a picture (often an actual map) on a web page that provides different “links” to other web pages, depending on where a user clicks on the image. There are two basic types of image maps: “client-side image maps” and “server-side image maps.” With client-side image maps, each “active region” in a picture can be assigned its own “link” (called a URL or “Uniform Resource Locator”) that specifies what web page to retrieve when a portion of the picture is selected. If the web page uses a server-side image map to present the user with a selection of options, then a redundant text link is necessary to provide access to the page for anyone not able to see or accurately click on the map. FYI, at EPA you must use the standard US and regional maps and associated code for displaying information and to link to local information when applicable. The standard maps have the accessibility requirements taken care of for you. The EPA standard for maps of the US is available at http://yos
