Google account image from email

Question

Is it possible to retrieve a Google account profile image like a Gravatar image?

I'm thinking it would be very handy to make a failover to Google image, if a gravatar is not found.

Answer 1

If you're able to get the Google user_id, you can retrieve the Google+ image.

Unfortunately, there doesn't appear to be an easy way to get the user_id from an email address.
