How to import photos from Facebook?

Question

I noticed when I visit photo printing websites, they ask you if you would like to import your photos from Facebook. How do they do it? Does Facebook provide API to import us

Answer 1

Sure you can retrieve photos from users that have added you application and agreed to share such information. First you retrieve the albums using the photos_getAlbums API call, then you can loop over album ids and call photos_get to retrieve photos for the albums.

  /**
   * get_albums()
   *
   * @param long $uid
   * @return array
   */
    function get_albums($uid=null)
    {
         if (empty($uid))
            $uid = $_REQUEST['fb_sig_user'];
        try
        {
            return $facebook->api_client->photos_getAlbums($uid,null);
        }
        catch (FacebookRestClientException $ex)

        {
            return array();
        }
    }


/**
   * get_photos()
   *
   * @param bool $bool_pids
   * @param mixed $aids (array of album ids or null)
   * @return array
   */
    function get_photos($bool_pids=true, $aids=null, $pids=null)
    {
        try
        {

            $p = $facebook->api_client->photos_get(null, $aids, $pids);
        }
        catch (FacebookRestClientException $ex)

        {
        }

    if ($bool_pids)
    {
        $pids = array();
        if (!empty($p))
        foreach($p as $p0)
            $pids[] = $p0['pid'];
        return $pids;
    }
    else
        return $p;
}
