The code used in your demo does not acquire the image associated with the video. How can I add an image to that widget text box?
Code used:
<a class="thickbox gk-video-block" href="//www.youtube.com/embed/Uh70E4hKTog?title=0&TB_iframe=true&width=640&height=480">Take a tour</a>
Widget style is set to Video
Thanks!
