title: prettyphoto plugin not playing videos of vzaar
body: <p>I've added prettyphoto plugin to my website to play videos on a popup. Videos on youtube and vimeo are working great but the videos on vzaar are not. I'm getting this error : "Image cannot be loaded. Make sure the path is correct and image exist." </p>
  
  <p>Is there anyone who knows a solution for this or any better offer for playing vzaar videos on a popup?</p>
  
  <p>Thanks in advance.</p>
