Hi,
You can use the custom admin columns to show the featured image in the listing posts/pages. Follow this documentation https://docs.metabox.io/extensions/mb-admin-columns/#custom-admin-columns
class My_Featured_Image_Columns extends \MBAC\Post {
public function columns( $columns ) {
$columns = parent::columns( $columns );
$position = 'before';
$target = 'title';
$this->add( $columns, 'featured_image', 'Featured Image', $position, $target );
// Add more if you want
return $columns;
}
public function show( $column, $post_id ) {
switch ( $column ) {
case 'featured_image':
the_post_thumbnail( [40, 40] ); //here
break;
// More columns
}
}
}
With the MB Builder, you can create a field with ID _thumbnail_id then show it as an admin column.
.
