The <area> tag is used to create regions on an image to be clickable or make something happen. So, a picture could have areas on it that would be clickable and link to different pages. The <area> tag is not used alone. It needs to be nested inside a <map> tag. So, it is a required tag needed with the <map> tag. The <area> tag will allow you to define a precise zone on an image to embed a script, link, etc.
