Switcher as I've written it: 

  <div id="mastheadimage"><a href="http://localhost/wordpress/"><img src="<?php if(trim(wp_title('',0))== 'Movies') { ?> 
	  http://localhost/wordpress/wp-content/graphics/movieheader.jpg
 <?php } elseif(is_category('9') || ('12') || ('13') || ('14')) { ?>
 
 http://localhost/wordpress/wp-content/graphics/businessheader.jpg
 
 <?php } else { ?>
http://localhost/wordpress/wp-content/graphics/mainheader.jpg

<?php } ?> " alt="header image here" /></a>

      </div>


CSS info related from style.php:


   	   #mastheadimage {
   	   clear:both;
           height:150px;
           padding: 0 0 0 5px;
           border-top:2px solid <?php echo $water_gray_1; ?>;
           border-bottom:2px solid <?php echo $water_gray_1; ?>;
