title: find unused images, css rules, js script blocks
body: <p>We have a fairly large asp.net website. </p>
  
  <p>The images, css and javascripts are property organized in the website project but as we are changing the look and feel of the website, I would like to know if there is a tool/add-in that will help me identify which images are not being used in the website.  </p>
  
  <p>I would like to find the same thing with css and javascript as well.  I have looked at dustme firefox extension but that only does css.</p>
