title: Rails 3.1 Asset pipeline - Why my images do not precompile for production?
body: <p>When running: </p>
  
  <pre><code>rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
  </code></pre>
  
  <p>Everything precompiles but not my <code>/app/assets/images/*</code></p>
  
  <p>I even tried adding this to my <code>environment/production.rb</code></p>
  
  <pre><code>config.assets.paths &lt;&lt; "#{Rails.root}/app/assets/images"
  </code></pre>
  
  <p>What's wrong? thanks!</p>
