Alineacion del header.gif

Wenas chicos. En mi pagina http://www.rockeando.net/sistema Si se fijan la imagen principal, esta a lineado a la izquierda, yo lo que quiero hacer es ponerlo en el centro, pero no se como:
El Index al abrise manda a un php llamado playing.php y a header.php, pero no se en cual de los dos me da para centrar la imagen aqui les dejo el codigo de ambos.

HEADER.PHP:
