Okay, I solved the puzzle. The following works:
big = StringIO.StringIO() # you have a StringIO
...
image.save(big, "JPEG", quality=70) # write something to the StringIO
...
# Photo is a model that has an image field
photo = Photo(user=creator)
# use getvalue because ContentFile just needs content
big_file = ContentFile(big.getvalue())
# use save method of image field, no other function!
photo.data.save("%s.jpg" % name, big_file)
