title: Smart Loading Images in a Slideshow + Lightbox
body: <p>I was looking for a responsive slideshow plugin that allow me to do a progressive images loading, and I found <a href="http://jquery.malsup.com/cycle2/demo/progressive.php" rel="nofollow noreferrer">cycle2</a>. This seems to use something like innerHTML to add images inside the slideshow and it´s that because either <code>prettyPhoto</code> or <code>PhotoSwipe</code> don't work with added images. Here is a similar problem: <a href="https://stackoverflow.com/questions/9010089/prettyphoto-wont-load-when-writing-href-using-document-write">prettyphoto wont load when writing href using document.write</a></p>
  
  <p>Somebody knows about similars plugins or how can add new images to lightbox index? </p>
