 * I added this function to my functions.php:
 *     ```
       <?php
           function is_tree($pid) {      // $pid = The ID of the page we're looking for pages underneath
           	global $post;         // load details about this page
           	$anc = get_post_ancestors( $post->ID );
           	foreach($anc as $ancestor) {
           		if(is_page() && $ancestor == $pid) {
                       return true;
           		}
           	}
           	if(is_page()&&(is_page($pid)))
                   return true;   // we're at the page or at a sub page
           	else
                   return false;  // we're elsewhere
           };
       ?>
       ```
   
 * and I am executing it outside of the loop:
 *     ```
       <?php
           if (is_tree('home')){
               echo '<img src = "' . $siteUrl . '/images/content_title_productivityOptimisation.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('partners')){
               echo '<img src = "' . $siteUrl . '/images/content_title_partner.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('blog')){
               echo '<img src = "' . $siteUrl . '/images/content_title_blog.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('contact')){
               echo '<img src = "' . $siteUrl . '/images/content_title_contact.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('productivity-tools')){
               echo '<img src = "' . $siteUrl . '/images/content_title_productivityTools.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('training-workshops')){
               echo '<img src = "' . $siteUrl . '/images/content_title_trainingWorkshops.jpg" alt = "Welcome Title" />';
           }
           elseif (is_tree('productivity-platforms')){
               echo '<img src = "' . $siteUrl . '/images/content_title_productivityPlatforms.jpg" alt = "Welcome Title" />';
           }else{
           }
       ?>
       ```
   
 * It is only working if is_page is true, rather than if it is a child of the parent
   identified in my if statements.
