        If there is a thumbnail, and it was sent as part of an
        application/json payload, then we need to unpack a thumbnail
        object payload and convert it to a Python ContentFile payload
        instead. We use a try/catch because the optional nature means
        we need to check using "if hasattr(request.data,'thumbnail'):"
        as we as "if request.data['thumbnail']" and these are pretty
        much mutually exclusive patterns. A try/pass make far more sense.
