That's one single image and a background image, too. Having different link areas on the same image is possible with image maps but this cannot be done on background images AFAIK. The single link that can be put on the header image is already done with a "trick", by laying an invisible layer over the image and making that clickable. For what you're trying to do I suggest that you remove the header image from the header through the theme options -> Header and then edit header.php by replacing
PHP Code:
<tr>
<!-- Header -->
<td id="header" colspan="<?php echo $cols; ?>">
<?php bfa_header_config($bfa_ata['configure_header']); ?>
</td>
<!-- / Header -->
</tr>
with
PHP Code:
<tr>
<!-- Header -->
<td id="header" colspan="<?php echo $cols; ?>">
<?php bfa_header_config($bfa_ata['configure_header']); ?>
</td>
</tr>
<tr>
<td><a href="link1"><img src="/image-left.gif" alt="" /></a></td>
<td><a href="/"><img src="/header-image.gif" alt="Aussie Pub Calls" /></a></td>
<td><a href="link2"><img src="/image-right.gif" alt="" /></a></td>
<!-- / Header -->
</tr>
The code above is made for a site with 3 columns and it would have to be 3 columns on all pages.
I'd also change the layout width to a fixed width of 1000px at Theme Options -> Layout -> Layout WIDTH and type (FLUID or FIXED)
