I have used this tutorial for 'sign in with google' on my website. http://tutorialzine.com/2012/08/build-a-one-click-registration-form-powered-by-google/
I am not a programmer really but just download the code in there and followed the steps in there. It works fine. Now I want all logged in users with their profile pic displayed as a list. This should be visible to anyone on the website. If a user logs out, he should be removed from the list. Can someone point me to an article or help me please?
