<?php
  $terms = get_terms( [
    'taxonomy' => 'services_tax',
    'hide_empty' => false,
  ] );
  if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
      foreach ( $terms as $term ) {
  
        $icon = pods_field( 'services_tax', $term->term_id, 'images', false);
        $icon_url = $icon[0]['guid'];
        $icon_thumb = pods_image_url ( $icon_url, 'large', 0, false ) ;
        $term_link = get_term_link($term);
       
      ?>

        <div class="services-item">
          <a href="<?php echo $term_link;?>">
            <img src="<?php echo $icon_thumb; ?>" alt="">
          </a>
        </div>

      }
  }
    
  ?>
