Get profile picture url in APi

The api call /api/v1/users/{user_id} does not provide a url to the users profile picture but does provide a timestamp for its last update. How can I get this image url?

The URL for that is /api/v1/users/{user_id}/image?time={last_picture_update}

Does anyone know if this is still working with api/v3?

Yes it still works. We use it in our mobile app.
