You've made some changes and those changes are not synced with DB. I've searched it on implementation level and this is no bug. Make sure you are using updated version of Pillow and image = models.ImageField(upload_to="whateverfolder/". Then sync using "python manage.py makemigrations" if you are using 1.8 and above. If you are using below 1.8 do the "python manage.py syncdb and your problem will be resolved. For future make it habit to sync models.
