Wycentrowanie (wyśrodkowanie) galerii – problem

Witam, mam tworzony przez zew. firmę szablon, ale niestety mnie zlali i już mi pomóc nie chcą po skasowaniu forsy. Próbowałem sam to ogarnąć na swoim localhoście ale nie idzie… Mianowicie chciałbym wycentrować galerię.

Żebym nie wyszedł na lenia grzebałem w sieci i próbowałem zmienić funkcję float: na none i center ale jak to robię to zamiast mi wycentować galerię to ją centruje, ale każda kolumna jest jedna pod drugą zamiast być wycentowane koło siebie.

CSS od galerii wygląda tak:

/*  ----------------------------------------------------------------------------
    default wordpress gallery
*/
/*  ----------------------------------------------------------------------------
    gallery
*/
