Example
In this sample, an area tag is written with the shape, coords, href, and alt attributes, for an image map associated with the "someDefaultPic.jpg" image.

The following <netui> tags...

    <netui:image src="someDefaultPic.jpg" alt="a default picture" usemap="#defaultMap"/>
    <map id="defaultMap" name="defaultMap">
        <netui:area shape="rect" coords="0,0,80,80" href="bigPicture.jsp" alt="big picture of the image"/>
    </map>

...output the following HTML:

    <img src="someDefaultPic.jpg" usemap="#defaultMap" alt="a default picture">
    <map id="defaultMap" name="defaultMap">
        <area href="bigPicture.jsp" shape="rect" alt="big picture of the image" coords="0,0,80,80">
    </map>
