How to access the Avatar from Google?

I've implemented OpenID-Login with Google. I can access the following attribute types 'contact/email', 'namePerson/first', 'namePerson/last' and 'pref/lang'. But I also wanna have the Google Account image/avatar. Concerning to the specs from http://www.axschema.org/types it should be 'media/image/default' or 'media/image/aspect11' but none of them work :(

Isn't it possible to access the image/avatar via OpenID?

Is the AX type something el开发者_运维知识库se?

Is there any other possibility to get that image?

According to the Google Federated Login page, Google supports only the following AX attributes:

• http://axschema.org/contact/country/home
• http://axschema.org/contact/email
• http://axschema.org/namePerson/first
• http://axschema.org/pref/language
• http://axschema.org/namePerson/last

As you can see, none of these contain user's avatar. So as far as I know, there is no way to get it.
