Any ideas on the actual call to "$api->callApi('content_photo' ...."? Is that the right call to use? If so, not sure what the arguments need to be.

I've also tried this, but to no avail:

   // Upload the file and add it
   $response = $api->callApi('content_attach', 'upload', array('file' => $fileInfo));

   $data = array(
     'parentId' => $albumId,
     'filedataid' => $response['filedataid'],
   );

   $response = $api->callApi('content_photo', 'add', array('data' => $data));
