title: Simulate a Click on an Image with usemap
body: <p>I know how to simulate a <code>click</code> event on a button using webbrowser control. However, I am not able to simulate the <code>click</code> event on an image with usemap with <code>mouseup</code> and <code>mousedown</code> events associated.</p>
  
  <p>how can I do it?</p>
  
  <p>Bellow is the html associated to the image and to the usemap:   </p>
  
  <pre><code>&lt;img src="http://www.temp.com/zoom_off.gif" id="photo_zoom" style="width: 39px; height: 23px; border: 0" alt="" usemap="#btnZCMap"&gt;
  
   &lt;area shape="rect" coords="2,2,19,25" href="#" onmouseover="doBtn('photo_zoom','in'); return false;" onmouseout="ZM=0; doBtn('photoe_zoom','off'); return false;" onmousedown="ZM=1; doZC(-1); return false;" onmouseup="ZM=0; return false;" onclick="return false;"&gt;
  </code></pre>
