I have a custom built blog that I want to show a contributors page with profile pictures for each contributing member. The organization uses google apps and all the contributing members have Google / Google+ profile pictures.
Is there a way I can use each user's e-mail address to lookup their profile picture and show that on their profile page on the blog? Or do I need to have them sign in with google before this is possible?
Is it any easier if I am doing this within the organization since we use google apps?
Basically, I can see all of these users' profile pictures in my g-mail account - so is there a way to grab the pictures to be used on the blog they contribute to as well?
