How can i get photo_url from janrain / RPX?

If somebody visit my site, i would like to extract the photo_url after jainrain / RPX authentication was happend on my site. But photo_url was not sent. I get the openid name, but not the photo address. I tried it with my gmail account, i put a photo to my profile, and i published it for anybody, but gmail doesn't s开发者_如何学JAVAent it for me. Why don't work it?

It's not required for an OpenID Provider to send any information about an authenticated user, even if you request it.

As far as I know Google does not support sending photo urls, though it does support sending names and email addresses.

So, there is solution. I found it here. If you sign up not with you google account, but your google profile (there is difference) then you will get the profile photo url also.
