title: How do I extract the largest image (by dimension) on a site given the URL?
body: <p>For instance, if I input:
  <a href="http://www.google.com/" rel="noreferrer">http://www.google.com/</a></p>
  
  <p>It would return:
  <a href="http://www.google.com/images/logos/ps_logo2.png" rel="noreferrer">http://www.google.com/images/logos/ps_logo2.png</a></p>
  
  <p>Using javascript/jquery. These sites would all be external. Thank you!</p>
