I'm using facebook graph API to upload photo on Facebook. => That's OK.
$response = (new FacebookRequest(
$session, 'POST', '/me/photos', array(
'source' => new CURLFile('upload/bg-design.jpg', 'image/png'),
'message' => 'Hello world',
'caption'=> 'Day la caption'
)
))->execute()->getGraphObject();
But it's always upload to XXXXXXX album (base on facebook app_ID).
Everybody has solution to post photo on Timeline Photos?
