"""This example gets all images and videos.

To upload an image, run upload_image.py. To upload video, see:
http://adwords.google.com/support/aw/bin/answer.py?hl=en&answer=39454.

The LoadFromStorage method is pulling credentials and properties from a
"googleads.yaml" file. By default, it looks for this file in your home
directory. For more information, see the "Caching authentication information"
section of our README.
