Google App Engine, GData & Picasa

Is there more comprehensive sample of creating Google App Engine App using GData Python Library to interact with Picasa Web Album, other than google guide from GA开发者_JS百科E here: http://code.google.com/apis/picasaweb/docs/1.0/developers_guide_python.html

For getting started with GAE and GData, you can take a look at: http://code.google.com/appengine/articles/python/retrieving_gdata_feeds.html

You should be able to update the samples code there to use PhotosService instead of DocClient.
