Create Google Script to Pull Profile Picture from Google Directory

I'm trying to create a google apps script where I can output to a google sheet all of the email addresses and links to profile pictures in my directory. I want to be able to access the user's google profile picture to use in my files. I looked briefly at the methods here, but could not get them to work. [login to view URL] It looks like someone may need to run Oauth2 in the google apps script to make this work, but I'm not sure. I will pay for the solution! Final product would be a script that would output all of the email addresses and profile picture URL's into a google sheet.
