title: Can you get someone's Google profile picture given only their gmail address?
body: <p>It seems like every api that Google has to get profile pictures requires the owner of the profile picture to be authenticated.</p>
  
  <p>I did find an endpoint from <a href="https://stackoverflow.com/questions/25606322/retrieving-a-users-public-google-gmail-picture">this</a> stackoverflow question :</p>
  
  <p><code>http://picasaweb.google.com/data/entry/api/user/${emailAddress}?alt=json</code></p>
  
  <p>It does work without authentication, but it seems to only work for older email accounts, and I can't find any documentation for it in Google's docs.</p>
  
  <p>Is there any other way to do this?</p>
