title: Django Imagekit processing the original image
body: <p>With version 1.1 I don't understand how I can preprocess the original image (by JUST using imagekit)</p>

  <p>Having a model like this:</p>
  
  <pre><code>class Photo(models.Model):
     original = models.ImageField(etcetera)
     thumbnail = ImageSpec(etcetera)
  </code></pre>
  
  <p>How do I for instance resize the original image? This was possible in previous imagekits, however the documentation insinuates I need another modelfield?</p>
