有时候我们需要在图片的某一个地方添加一个url，最好的办法就是为图片添加热点，
实例：
<img src="zhaobiaowang.jpg" width="1002" height="750" border="0" usemap="#Map" /> <map name="Map" id="Map"> <area shape="rect" coords="95,376,323,434" href="http://www.hnzbtb.com" target="_blank" /> <area shape="rect" coords="527,371,752,436" href="http://www.sdzbw.com" target="_blank" /> <area shape="rect" coords="310,446,538,507" href="http://www.ssrshr.com" target="_blank" /> <area shape="rect" coords="344,280,519,381" href="http://www.cnssrs.com/" target="_blank" /> <area shape="rect" coords="74,37,631,81" href="http://www.ssrshr.com" target="_blank" /> <area shape="rect" coords="70,480,300,540" href="http://nmgzb.ssrszb.com" target="_blank" /> <area shape="rect" coords="527,580,800,436" href="http://sxzb.ssrszb.com" target="_blank" /> </map>
