You can save the file and assign its path (relative to MEDIA_ROOT) to destination field manually.

thumb_path = 'uploads/1_small.jpg'
thumb_image_fit.save(os.path.join(MEDIA_ROOT, thumb_path), 'JPEG', quality=75)
newfile.thumbnail = thumb_path

Surely you’ll need to do all Django’s stuff manually – check if the file exists, modify name if it does, and so on.
