Hey, I’ve been having the exact same problem, but I figured it out.
In header.php you have to change the header image size AND its alignment, which is located here:
#header
{ background: url(“<?php bloginfo(‘stylesheet_directory’); ?>/images/kubrickheader.jpg”) no-repeat bottom center; }
Change “bottom” to “top”.
You also have to change a few things in style.css: the height variable under “#header” and “#headerimg” and the text alignment settings found in the section marked “/* Begin Headers */”.
