title: Linkedin - How can i get big profile picture
body: <p>I am trying to harvest some profile photo's
  which is no problem
  after authentication an array is returned and i can use the value of 'pictureUrl' which contains the location of the small profile photo.</p>
  
  <p>What i can't seem to find in the documentation is the url for the larger profile photo (which is shown after clicking on the small photo of a person's page)</p>
  
  <p>Does anybody know how/where to get this bigger picture?</p>
  
  <p>thanks</p>
