title: how to modify slimbox to close by clicking on expanded image
body: <p>I am using Slimbox 1.71 for MooTools 1.2 ( <a href="http://www.digitalia.be/demo/slimbox/" rel="nofollow noreferrer">Demo</a> )<br />
  I would like to close the expanded Image if I click on the expanded image itself.</p>
  <p>How would I do that?</p>
