title: Auto add magnifying icon to thumbnails
body: <p>I'm looking to add a centered magnifying glass icon to my portfolio gallery. 
  Like the effect at <a href="http://jquerystyle.com/gallery" rel="nofollow noreferrer">http://jquerystyle.com/gallery</a>.
  I know I can do this with css at each instance, but I would like to find a way to do it automatically. Any jquery plugins that do this?</p>
  
  <p>Thanks!</p>
