Getting Google+ profile picture url with user_id

Question

I know that lots of social network APIs provide a way to construct a url to the profile picture of a user, using their user_id or username. For Facebook it looks like this:

http://graph.facebook.com/user_id/picture?type=square

Now is there something like this for Google Plus? Or any other way to get user's pic without an API call??

Answer 1

Google had changed their policy so the old way for getting the Google profile image will not work now, which was

https://plus.google.com/s2/photos/profile/(user_id)?sz=150

New Way for doing this is

Request URL

https://www.googleapis.com/plus/v1/people/115950284...320?fields=image&key={YOUR_API_KEY}

That will give the Google profile image url in json format as given below

Response :

{
    "image": 
    {
         "url": "https://lh3.googleusercontent.com/-OkM...AANA/ltpH4BFZ2as/photo.jpg?sz=50"
    }
}

More parameters can be found to send with URL which you may need from here
