Fetch the user albums and photos

Hi, 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.
