Fetch the user albums and photos

I am using omni-auth for the user authentication and logged in the user
via access token.
But like facebook i want to fetch the user profile information and all
the albums he/she uploaded and images belongs to that albums, than save
the public url to my own database.
I found fb_graph a very good gem to use FB Graph search but i could not
find any Gem that helps me to extract images,albums from Google+.

Any suggestions and gem that can solve this problem are welcome.
