title: Rails 3.1 and Image Assets
body: <p>I have put all my images for my admin theme in the assets folder within a folder called admin. Then I link to it like normal ie.</p>
  
  <pre><code># Ruby    
  image_tag "admin/file.jpg" .....
  #CSS
  .logo{ background:url('/assets/images/admin/logo.png');
  </code></pre>
  
  <p>FYI. Just for testing I am not using the asset_path tag just yet as I have not compiled my assets.</p>
  
  <p>Ok all good so far until I decided to update an image. I replaced some colors but on reload the new styled image is not showing. If I view the image directly in the browser its still showing the old image. Going one step further I destroyed the admin images folder. But it has broken nothing all the images are still being displayed.  And yes I have cleared my cache and have tried on multiple browsers.</p>
  
  <p>Is there some sort of image caching going on?  This is just local development using pow to serve the pages.</p>
  
  <p>Even destroying the whole images folder the images are still being served.</p>
  
  <p>Am I missing something?</p>
