title: Django Rest Framework with easy-thumbnails
body: <p>With a normal ImageField, serializing the URL is simply <code>image = serializers.ImageField()</code>. What should it look like when using easy-thumbnails?</p>
  
  <p>So far, I've only found a function for getting the URL: <a href="https://stackoverflow.com/questions/16174675/django-easy-thumbnails-accessing-image-urls">Django easy_thumbnails accessing image URLs</a>
  Using this in a serializer would require a SerializerMethodField, which is an unsatisfying solution. I'm looking for a solution that's as efficient/performant as practical, and on one line.</p>
