The App Engine users API is separate from the authorization system required by Google Data APIs (like picasaweb). A user will need to authorize your app to access their picasaweb data, so I recommend using AuthSub. It is still a good idea to have users log in to your app, because you can then store the long lived AuthSub session token in the datastore and associate it with the current user. By reusing the session token, users will not have to go through multiple redirects to authorize your app each time that you app accesses picasaweb, the user will just need to do the redirects the first time they use your app.
