title: Delete unused product images in magento
body: <p>The <a href="http://www.magentocommerce.com/magento-connect/defcon2/extension/1147/image-clean" rel="noreferrer">image-clean</a> module lists unused images under /media/catalog/product and let you delete them.
  Is there a script that automatically delete unused images without user interaction?
  I want to run this script manually or use a cron job every night.</p>
  
  <p>Thanks</p>
