title: css opacity not working in IE7
body: <p>I have this test page : <a href="http://jsfiddle.net/VWnm9/7/" rel="noreferrer">http://jsfiddle.net/VWnm9/7/</a>. The image is correctly faded on all my computers running IE7 or IE8, except for one computer that runs IE7 and doesn't fade the flower, even in noext mode.</p>
  
  <p>The page is :</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
          "http://www.w3.org/TR/html4/loose.dtd"&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;style type="text/css"&gt;
          body {
              background: blue;
          }
          img {
              filter: alpha(opacity=10);
              opacity: 0.1;
          }
      &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;img src="http://upload.wikimedia.org/wikipedia/commons/c/c3/Extracted_pink_rose.png" /&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Does anybody have an idea why?</p>
