Brilliant, thanks! Still getting the hang of filters.

Pasting the whole code here in case it helps someone else:

/* THIS CHANGES FEATURED IMAGE TO 'Mug Shot' ON PAGES OF CUSTOM POST TYPE 'plc_person', ADDS A DESCRIPTION AND MOVES THE METABOX TO IMMEDIATELY UNDER THE MAIN CONTENT */

/* Put the meta box setup function on the post editor screen. */
add_action( 'load-post.php', 'plc_person_meta_boxes_setup' );
add_action( 'load-post-new.php', 'plc_person_meta_boxes_setup' );
/* Meta box setup function. */
function plc_person_meta_boxes_setup() {

  /* Change featured image meta box */
  add_action('do_meta_boxes', 'change_featured_image_box');
}
/* To be displayed on the person editor screen. */
function change_featured_image_box() {
	remove_meta_box( 'postimagediv', 'plc_person', 'side' );
	add_meta_box('postimagediv', __('Mug Shot'), 'post_thumbnail_meta_box', 'plc_person', 'normal', 'high' );
}

/* Display post thumbnail meta box including description */
add_filter( 'admin_post_thumbnail_html', 'plc_post_thumbnail_add_description', 10, 2 );

function plc_post_thumbnail_add_description( $content, $post_id ){
$post = get_post( $post_id );
$post_type = $post->post_type;
    if ( $post_type = plc_person) {
  		$content .= "<p><label for=\"html\">This needs to be a head shot of this person stood in front of the wall in the hall. Crop to 300px x 300px with half a brick above and below their head.</label></p>";
		return $content;
		return $post_id;
	}
}

/* Rename 'Featured Image' as 'Mug Shot' */
function plc_person_change_labels($labels) {
	$labels->featured_image  = 'Mug Shot';
    $labels->set_featured_image  = 'Add Mug Shot';
    $labels->remove_featured_image   = 'Remove Mug Shot';
    $labels->use_featured_image  = 'Use as Mug Shot';

	return $labels;
}
/* This is the filter being applied in wp-includes>post.php */
/* $labels = apply_filters( "post_type_labels_{$post_type}", $labels ); */

add_filter( "post_type_labels_plc_person", 'plc_person_change_labels', 10, 1 );

I’ve got it sorted, thanks. Not related to my original problem

I’ve put your points here: https://ww.wp.xz.cn/support/topic/theme-gridiculous-custom-menu-wizard-plugin-issues?replies=2#post-6095628

Hopefully the Gridiculous authors will pick it up

Thanks again,
Rachel

Thanks for all your efforts on this, wizzud.

I did look into making a child theme awhile ago, but the instructions I found only said what to do if you’re using a theme that does not use wp_enqueue_style() in its functions.php file. But gridiculous does, and I couldn’t get the child theme to work.

I just don’t think I could do the other things you suggest and be sure I wasn’t wrecking things.

I will email the authors of Gridiculous and see what they say.

Thanks a lot, the app is great and the support you provide even better!

Rachel
