Currently i'm using something like this:
images = Image.all()
count = images.count()
random_numb = random.randrange(1, count)
image = Image.get_by_id(random_numb)
But it turns out that the ids in the datastore on AppEngine don't start from 1. I have two images in datastore and their ids are 6001 and 7001.
Is there a better way to retrieve random images?
