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 sent it for me. Why don't work it?
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.
