title: how do i get facebook photo of public user in php
body: <p>I want to retrive images of facebook public profiles by searching an email.
  My company has a CRM of about 5 million clients in our system.
  I want to use the facebook Graph API but without asking the users to login to facebook.
  is it possible to login back end with one user email and password to facebook api and search for public profiles?</p>
  
  <p>by the way i used this example that makes a simple search but it retrived a captcha after i searched a lot of users</p>
