One database, multiple subdomains, a different header image for each?
 

I offer almost the same project with some slight tailoring in a few different major cities, and in order to allow me to only work off of one database for the sake of maintenance time and my sanity, I'm hoping to have several different subdomains all use the same database.

I think I've got this 99% figured out, but the last thing I'm having difficulty with that's preventing this from working is the header. I'd like to have a different, customized header image for each subdomain.

I'd ideally like to do something where instead of just pulling the image out of the images/header/ directiory, it would just use something like this: <img src="<?php echo form_option('siteurl') . '/custom/images/header/headerimage.jpg'; ?>

How can I hack Atahualpa to make it do this? Any help would be greatly appreciated.

the header code is in bfa_header_config.php
