title: GIF slider in flexslider, how to begin the gif only when on slider
body: <p>Right now I have a flexslider with four slides. The third slider is a gif rather than a jpg like the others. 
  The issue I am having is that this third gif slider apparently starts immediately when the page is reached as opposed to when you actually get to that slider. By the time one clicks through the first two sliders, the gif is just about finished.  </p>
  
  <p>Anyone have any idea as to how I would begin a GIF only when one reaches that
   slider?</p>
