title: Browser Caching with Paperclip
body: <p>I have a quite long slideshow of images, all rendered via the awesome Paperclip. 
  Those images won't change very often, so I'd like to make use of browser caching. 
  Problem is Paperclip appends a unique load id to the image url. 
  (eg: pancakes.png?1275839986)</p>
  
  <p>Is there any way to prevent this from happening?</p>
  
  <p>Thanks!</p>
