title: Tumblr Photoset Captions not working with Magnific Popup
body: <p>I am using a <code>Tumblr</code> theme that has <code>Magnific Popup</code> pre-installed.</p>
  
  <p>The problem is that the individual <code>caption</code> of a <code>photo</code> in a <code>Photoset</code> does not appear anywhere.
  I am guessing that the script does not know where to take that information from (<code>Tumblr</code> hasn't been very helpful with their ambiguous <code>{JSPhototsetLayout}</code> either).</p>
  
  <p>Do you have any idea how to solve this?
  Thank you so much.</p>
