title: Do SVG-enabled browsers ignore alternative images (when included in object tags)?
body: <p>An illustration that I want to include in a site is 28.1 times smaller in SVG format than the same illustration saved as a PNG.</p>
  
  <p>Unfortunately, I have to cater for browsers that aren't SVG-enabled. So I'm still including the PNG as an alternative, like so:</p>
  
  <pre><code>&lt;object type="image/svg+xml" data="illustration.svg"&gt;
    &lt;img src="illustration.png" alt="alternate description"&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>Will SVG enabled browsers ignore the PNG in this case or will it still get loaded in the background somehow? (i.e. am I saving on overall load time?)</p>
