title: Simple photo gallery gem
body: <p>Is there any rails gem, that implements simple photo gallery.</p>
  
  <p>The required features are following:</p>
  
  <ul>
  <li>organizing photos to albums;</li>
  <li>admin interface, that allows to upload several photos at once, edit title and description.</li>
  </ul>
  
  <p>I've found <a href="http://balderapp.com/">http://balderapp.com/</a>, but this is an app (not a gem). Also, it is quite heavy, because of tags, places etc. These models can interfer with existing things in my project.</p>
