How to display Woocommerce Category image?

To display the category image for the currently displayed category in archive-product.php, use the current category term_id when is_product_category() is true:

// verify that this is a product category pageif ( is_product_category() ){    global $wp_query;    // get the query object    $cat = $wp_query->get_queried_object();    // get the thumbnail id using the queried category term_id    $thumbnail_id = get_term_meta( $cat->term_id, 'thumbnail_id', true );     // get the image URL    $image = wp_get_attachment_url( $thumbnail_id );     // print the IMG HTML    echo "<img src='{$image}' alt='' width='762' height='365' />";}

get_woocommerce_term_meta is depricated since Woo 3.6.0.

so change

$thumbnail_id = get_woocommerce_term_meta($value->term_id, 'thumbnail_id', true );

into: ($value->term_id should be woo category id)

get_term_meta($value->term_id, 'thumbnail_id', true)

see docs for details:https://docs.woocommerce.com/wc-apidocs/function-get_woocommerce_term_meta.html

From the WooCommerce page:

// WooCommerce – display category image on category archiveadd_action( 'woocommerce_archive_description', 'woocommerce_category_image', 2 );function woocommerce_category_image() {    if ( is_product_category() ){      global $wp_query;      $cat = $wp_query->get_queried_object();      $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );      $image = wp_get_attachment_url( $thumbnail_id );      if ( $image ) {          echo '<img src="' . $image . '" alt="" />';      }  }}
