title: Image and Checkbox Inside Label in Internet Explorer
body: <p>I have the following html:</p>
  
  <pre><code>&lt;label&gt;
      &lt;img src="..." /&gt;
      &lt;input type="checkbox" .../&gt;
  &lt;/label&gt;
  </code></pre>
  
  <p>In Chrome and Firefox, clicking the <code>img</code> will check/uncheck the checkbox. But in IE8, it doesn't respond when the image is clicked.</p>
  
  <p>Is my html tag invalid?</p>
