Custom taxonomy thumnbails for custom post type on category page

Question

I need display the custom taxonomy thumnbail and name on category page. I have this code :

<h1><?php single_cat_title(); ?></h1>
    <?php

    $taxonomy = 'kategorie_goralskie';
    $terms = get_terms($taxonomy, array('parent' => 0, 'orderby' => 
    'meta_value', 'order' => 'DESC') ); // Get all top level terms of a 
    taxonomy

    if ( $terms && !is_wp_error( $terms ) ) :
   ?>

   <?php if ( have_posts() ) : ?>
   <?php while ( have_posts() ) : the_post(); ?>
    <div class="col-md-3">

        <a href="<?php the_permalink(); ?>"><?php the_title();?></a>
    </div>
   <?php endwhile; ?>
    <?php endif; ?>

It shows only name of child (its ok) I must show thumnail too. How i can do it ? I tried in many ways enter image description here

In front-page.php everything is ok, i see taxonomy parent - just look : enter image description here

You need to call the_post_thumbnail function somewhere in your loop to display thumbnail. you can pass the size of the thumbnail you whant in function parameter.

See the detail of this function here : https://developer.wordpress.org/reference/functions/the_post_thumbnail/
