title: Rails 3.1: alias /images to /assets directory
body: <p>I'm upgrading to rails 3.1 and I need to have the /images directory be an alias to /assets. Is this possible? The reason being I don't want emails that I have sent out to clients which have direct links to files in /images to break. </p>
  
  <p>Is this possible at the web server level? I'm on nginx.</p>
