I have got a little of the taxonomy employed in my WordPress site that are responsible for items. I have got Pages organized because the product groups after which I produced a custom publish type for my items to become organized much more.

For that parent page, I wish to pull all pictures (particularly the Featured Picture of the page) all the kids pages.. However, they are not directly children, but pages during my custom publish type.

By now, I have displayed the kid page game titles around the parent page using with 'campaign' being my custom publish type's title:

$args = array(
'title_li'=> __('')
wp_list_pages( $args ); 

It is possible to similar method to pull all featured images of the certain publish-type?

Performs this assist you to?

$mypages = get_pages('

if($mypages) {
    echo '<ul>';
    foreach($mypages as $page) { ?>
        <li class="page_item">
            <?php echo get_the_post_thumbnail($page->ID, 'thumbnail'); ?>
            <a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a>
        </li> <?php
    echo '</ul>';
} ?>
