title: Does 'load' event get called on img 302 redirects? How to test for this?
body: <p>I think that the browser is calling the "load" event on the very first HTTP response it gets from loading an image (as long as it's not a 500 or another erroneous code)</p>
  
  <p>For example</p>
  
  <ol>
  <li>Img url returns a 302 Moved Temporarily</li>
  <li>Browser calls erroneously "load" event on img tag</li>
  <li>2nd HTTP request made, gets 200 success</li>
  <li>Image is now actually loaded</li>
  </ol>
  
  <p>Does anyone know a way to test for this?</p>
  
  <p>Maybe I'll go digging into browser code..</p>
