title: jquery-datatables-rails sort arrows not showing up when deployed to Heroku
body: <p>Running the cedar stack.  When I deploy, the dataTables works but none of the sort arrows show up.
  The files not showing up are:
      sort_asc.png
      sort_both.png
      sort_desc.png</p>
  
  <p>They appear when running locally on my development environment. I found this <a href="https://stackoverflow.com/questions/9439562/images-desapears-after-deploy-rails-3-1-3-on-heroku-cedar">Images desapears after deploy Rails 3.1.3 on Heroku Cedar</a> and it looks like a similar issue, but I am somewhat new to rails and don't know how to apply that since I'm using a gem.</p>
  
  <p>Any ideas?</p>
