I am using the code below for my logo in the header that can appear above or below the text and slogan. It aligns itself to the left. How do I get it to align to the center like the text and slogan? Missing something in the CSS stylesheet file?

Thank you.

<div class="art-Header">

<div class="art-Header-jpeg"></div>

<div class="art-Logo"> <img src="logo location"align="center"/>

<h1 id="name-text" class="art-Logo-name">

<a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>

<div id="slogan-text" class="art-Logo-text">

<?php bloginfo('description'); ?><img src="logo location"align="center"/></div>

</div>
