Need help- Cleaker theme-header img by category

Hello all-

I know that code for this has been put up here before, but I can’t get this to work. I think there is an easier way to do this with an array, but I can’t figure it out. HELP! PLEASE! AHHHHH!!!

<?php /* Calls the header image for each category - necessary code */
$category = $wp_query->category;
if ( is_category('Belize')) {
$imgurl = "http://www.h2outfitters.com/wordpress/wp-content/themes/Cleaker/images/header1.jpg";

If anyone can help clean this code up and make it correctly, I’d be eternally grateful. Right not it works for the first category, and any category not included in these. I’d like to cut it down to Category parents, too, if possible (about, trips, bed and breakfast trips are currently some of the parent categories).

Thanks in advance,
