title: Alternative for background-size:cover in IE7+
body: <p>I have a background image on the body of my web page. I have used <code>background-size:cover</code> so that the image stretches across the body whilst maintaining the aspect ratio of the image. I would like this to be the same for IE7 + IE8.</p>
  
  <p>I have looked around and seen the following code:</p>
  
  <pre><code>filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
      src='AutumnWinter_4.jpg',
      sizingMethod='scale');
  -ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
      src='AutumnWinter_4.jpg',
      sizingMethod='scale')";
  </code></pre>
  
  <p>But this doesn't preserve the aspect ratio, which is really bad for the website we are aiming at.</p>
  
  <p>Is there any way to do this? Without hitting up jQuery?</p>
