I use the example upload_image.py
catch error:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte 

if, I change open(image_filename, 'r') to open(image_filename, 'rb')
I got error:

suds.WebFault: Server raised fault: 'Unmarshalling Error: cvc-datatype-valid.1.2.1: 'b'/9j/4AAQSkZJRgABA... 

so what is the right way to upload image or create ImageAd

My python version is python 3.5.2 and system is ubuntu 16.04 and image is download from http://goo.gl/9JmyKk
