title: How to create a dotted shadowy effect on an image with CSS?
body: <p>I would like to create the effect that can be seen on the website <a href="http://www.murmure.me/" rel="nofollow">http://www.murmure.me/</a> when you hover on their images.</p>
  
  <p>I know They use two different images but I would like to be able to this effect without 2 images, just with ONE picture (the one without the dots) and by using CSS. Is it possible ? </p>
