Trying to center header image, added ( align="center" ) but it did not work

 

<table border="0" width="100%" cellspacing="0" cellpadding="0">

<tr class="header">

<td align="center" valign="middle"><?php echo tep_image(DIR_WS_IMAGES . 'gateway4logo.JPG'); ?></td>

<td align="right" valign="bottom"><?php echo '//<a href="' . tep_href_link(FILENAME_ACCOUNT, '', 'SSL') . '">' . tep_image//(DIR_WS_IMAGES . 'header_account.gif', HEADER_TITLE_MY_ACCOUNT) . '</a> //<a href="' . tep_href_link(FILENAME_SHOPPING_CART, '', 'NONSSL') . '">' . tep_image//(DIR_WS_IMAGES . 'header_cart.gif', HEADER_TITLE_CART_CONTENTS) . '</a> //<a href="' . tep_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . tep_image//(DIR_WS_IMAGES . 'header_checkout.gif', HEADER_TITLE_CHECKOUT) . '</a>'; ?> </td>
