title: Docker error permission denied and where do the images end up after pull?
body: <p>I have two questions.</p>
  
  <p>1) I get an error when I run:</p>
  
  <pre>
  karl@karl-laptop:~o docker pull node
  2015/04/29 01:39:41 Post http:///var/run/docker.sock/images/create?fromImage=banode&tag=: dial unix /var/run/docker.sock: permission denied
  </pre>
  
  <p>2) When I pull down images, where are they located?</p>
