Here is how I create images for testing purposes, I found this solution in the SO, maybe it helps you. 

from StringIO import StringIO
from PIL import Image

.....
def create_image_file(self):
    image_file = StringIO()
    image = Image.new('RGBA', size=(50, 50), color=(256, 0, 0))
    image.save(image_file, 'png')
    image_file.seek(0)
    return ContentFile(image_file.read(), 'test.png')
