Display Different Header Images
Problem
I want to display a different header image if the page is a SimplePages page.
Solution
In the theme’s header.php file, usually in theme/common/header.php, add the following code to change the image if the page is a SimplePage. This example comes from default theme:
<header role="banner">
<div id="site-title">
<?php if ($bodyclass=='page simple-page'):?>
<img src="my_image.jpg" alt="my_alt_text"/>
<?php else: ?>
<?php echo link_to_home_page(theme_logo()); ?>
<?php endif ?>
</div>
</header>
In the site title div, the original code for the theme was:
<header role="banner">
<div id="site-title">
<?php echo link_to_home_page(theme_logo()); ?>
</div>
</header>
The changes here check whether we’re on a simple page, and if so will display your image of choice. Otherwise, it instead displays the theme logo.
