title: onmouseover javascript opacity for IE8 and IE7
body: <p>This is what I have so far:</p>
  
  <pre><code>&lt;img src="images/test.jpg" 
  class="black" 
  
  onmouseout="this.style.opacity=1;
  this.filters.alpha.opacity=100;
  this.style.filter='progid:DXImageTransform.Microsoft.Alpha(Opacity=100)"
  
  onmouseover="this.style.opacity=0.3;
  this.filters.alpha.opacity=30;
  this.style.filter='progid:DXImageTransform.Microsoft.Alpha(Opacity=30)'" 
  /&gt;
  </code></pre>
  
  <p>It's works in FF and Safari, but not IE 7 or 8.<br />
  Suggestions?</p>
