title: Localhost: Image from origin 'null' has been blocked from loading by Cross-Origin Resource Sharing policy
body: <p>I'm opening the page on two computers, both ip and localhost tried:</p>
  
  <p>Strangely, for one computer, the <code>http://192.168.1.100/dev</code> didn't work and <code>http://localhost/dev</code> did. For the other, neither worked. It says,</p>
  
  <blockquote>
    <p>Image from origin 'null' has been blocked from loading by Cross-Origin Resource Sharing policy: Received an invalid response. Origin <code>'http://localhost'</code> is therefore not allowed access.</p>
  </blockquote>
  
  <p>None of the answers I found seem to work. And I don't understand why it only worked on <code>localhost</code> on one computer. Any suggestions?</p>
  
  <p>Edit:</p>
  
  <ol>
  <li>Browser: Chrome Version 34.0.1847.11 beta</li>
  <li><code>http://127.0.0.1/dev</code> didn't work either</li>
  <li>The uploaded version on server didn't work either</li>
  </ol>
