title: Images broken after uploading Rails app to heroku
body: <p>Shows fine locally. But when I upload to Heroku, I get the following:</p>
  
  <p><a href="https://i.stack.imgur.com/TNfnI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/TNfnI.png" alt="enter image description here"></a></p>
  
  <pre><code>&lt;%= image_tag('logo-red.png') %&gt;
  </code></pre>
  
  <p>and it's located in assets/images/</p>
  
  <p>I'm not using Turbolinks. Do I need to run a command on Heroku to solve this or is there some config setting I'm missing?</p>
  
  <p><strong>edit 1: tried running <code>heroku run rake assets:precompile RAILS_ENV=production</code></strong></p>
  
  <p><strong>edit 2: response from heroku staff:</strong></p>
  
  <p><em>It looks like your app is properly compiling that image:
  ~/public/assets $ pwd
  /app/public/assets
  ~/public/assets $ ls | grep logo-red
  logo-red-a07050d882e1dba431cef2130d39f929c611eaf8b0ec3c50db0742ddccb14d93.png</em></p>
  
  <p><strong>edit 3: See attached screenshot</strong>
