title: Uploading photo to another user's profile in Facebook using PHP
body: <p>Can you post a photo to the wall of a <em>friend</em> of the logged-in user using the FB Graph API? I could find no posts that answered this exact question but if there are please point me in the right direction.</p>
  
  <p>I have tried the code found in <a href="https://stackoverflow.com/questions/2718610/">answers to this question</a> to post a photo, but no matter what user id is used in the call to api, the photo gets added to an album on the logged-in user's profile.</p>
  
  <p>Is it possible to post a photo to another user's profile - just like one any user can manually add to someone's Wall Photos? i.e, a post that will have type: "photo" in the graph API instead of type "link".</p>
