Yes, you will pass the record id of the photo(s)from the controller to
your view.
for example to display photos for a certain user:
// Controller
(assuming that Photo $belongsTo User)
$user = $this->User->Photo->find('all', array('conditions' =>
array($conditions)));
$this->set(compact('user'));
// In your view
$photo_id = $user['Photo']['id'];
The user information for that photo will be available in the array as
well.
