title: django-imagekit tutorial fail - not creating thumbnails
body: <p>I've tried according to <a href="https://github.com/jdriscoll/django-imagekit/blob/develop/README.rst" rel="nofollow">this tutorial</a> but failed. I've got everything copied <strong>exactly</strong> as it is in tutorial. The problem is that ImageKit is not creating thumbnails (both display and thumbnail images).</p>
  
  <p>Here is some detail:</p>
  
  <pre><code>&gt;&gt;&gt; from myapp.models import Photo
  &gt;&gt;&gt; p = Photo.objects.all()[0]
  &gt;&gt;&gt; p.original_image.url
  'photos/lena.jpg'
  &gt;&gt;&gt; p.display.url
  Traceback (most recent call last):
    File "&lt;console&gt;", line 1, in &lt;module&gt;
  AttributeError: 'Photo' object has no attribute 'display'
  &gt;&gt;&gt; p.thumbnail_image.url
  Traceback (most recent call last):
    File "&lt;console&gt;", line 1, in &lt;module&gt;
  AttributeError: 'Photo' object has no attribute 'thumbnail_image'
  </code></pre>
