How to replace the kubric header image with a better image in WordPress 2.7.1.
1. First I replaced the kubricheader.jpg image with my own. I kept the image dimensions the same (760×200 pixels).
2. In header.php I replace the header div with the following:
<div id="header">
<a href="<?php echo get_option('home'); ?>"><div id="headerimg"></div></a>
</div>
This worked very nice. I would rather use a theme but I was in a time crunch.
