title: HTML/IE: stretch image to fit, preserve aspect ratio
body: <p>In an HTML window, I am setting a custom body </p>
  
  <pre><code>&lt;img src="file://[filename]"&gt;
  </code></pre>
  
  <p>to display an image.</p>
  
  <p>Now I want to strectch the image to fit the available window, but preserve aspect ratio. </p>
  
  <pre><code>&lt;img src="file://[filename]" width="100%" height="100"&gt;
  </code></pre>
  
  <p>stretches but also distorts the image.</p>
  
  <p>Is there some HTML trickery to do that? 
  IE only solution is fine, since this is in a hosted broweser control.</p>
