title: Get Vimeo thumbnail for video using jQuery
body: <p>I've found similar questions but none of the answers show clearly and easily how to get a thumbnail for a vimeo video using jQuery and JSON. If anyone can help that would be great, here is what I've got but it shows nothing at the moment.</p>
  
  <pre><code>var vimeoVideoID = '17631561';
  var videoCallback = 'showThumb';
  
  $.getJSON('http://www.vimeo.com/api/v2/video/' + vimeoVideoID + '.json?callback=' + videoCallback,
  
  function(data){
  $(".thumbs").attr('src',data[0].thumbnail_large);
  });
  </code></pre>
  
  <p>Thanks in advance.</p>
