url_h, url_k uses a different secret

    def url_q(r); PHOTO_SOURCE_URL % [r.farm, r.server, r.id, r.secret, '_q', 'jpg'] end
    def url_n(r); PHOTO_SOURCE_URL % [r.farm, r.server, r.id, r.secret, '_n', 'jpg'] end
    def url_c(r); PHOTO_SOURCE_URL % [r.farm, r.server, r.id, r.secret, '_c', 'jpg'] end
    # below two functions are not correct
    def url_h(r); PHOTO_SOURCE_URL % [r.farm, r.server, r.id, r.secret, '_h', 'jpg'] end
    def url_k(r); PHOTO_SOURCE_URL % [r.farm, r.server, r.id, r.secret, '_k', 'jpg'] end
