title: How to allow users with the member role to upload images as public in an Openstack Cloud?
body: <p>I've tried changing the /etc/glance/policy.json and setting the following:</p>
  
  <pre><code>"publicize_image": "role:member",
  </code></pre>
  
  <p>And then restarting both the glance-api and glance-registry services but of course that would be too easy so it doesn't work :)</p>
  
  <pre><code>openstack image create --file gammy_image.iso JACOBS-GAMMY-IMAGE --public
  403 Forbidden
  You are not authorized to complete publicize_image action.
      (HTTP 403)
  </code></pre>
