I found this code at wordpress codex, my question is how do I use this code?
<?php
if ( is_page('about') || $post->post_parent == '2' ) {
// the page is "About", or the parent of the page is "About"
$bannerimg = 'about.jpg';
} elseif ( is_page('learning') || $post->post_parent == '56' ) {
$bannerimg = 'teaching.jpg';
} elseif ( is_page('admissions') || $post->post_parent == '15' ) {
$bannerimg = 'admissions.jpg';
} else {
$bannerimg = 'home.jpg'; // just in case we are at an unclassified page, perhaps the home page
}
?>
How do I make it work with my <div>:
<div id="image"><img src="BANNERHERE></div>
