Display Individual Product Images in Grouped Product

Of course. Here’s the login information. Thank you.

Thank you very much, guys, but I finally managed to get it working after trying in several different ways, using a bit of code in the functions.php file:

// Añade la miniatura al lado izquierdo del título en la tabla de productos agrupados
add_filter( 'woocommerce_grouped_product_list_column_label', function ( $label, $product ) {

    if ( ! $product || ! is_a( $product, 'WC_Product' ) ) {
        return $label;
    }

    $product_id = $product->get_id();

    // Miniatura (o placeholder si no hay imagen)
    $thumb_html = get_the_post_thumbnail(
        $product_id,
        'woocommerce_thumbnail',
        [ 'class' => 'grouped-thumb' ]
    );
    if ( ! $thumb_html ) {
        $thumb_html = wc_placeholder_img( 'woocommerce_thumbnail' );
    }

    // Enlace a la ficha del producto
    $thumb_linked = sprintf(
        '<a class="grouped-thumb__link" href="%s" aria-label="%s">%s</a>',
        esc_url( get_permalink( $product_id ) ),
        esc_attr( $product->get_name() ),
        $thumb_html
    );

    // Estructura: imagen + texto del label
    $new = sprintf(
        '<div class="grouped-label-with-thumb">%s<div class="grouped-label-text">%s</div></div>',
        $thumb_linked,
        $label
    );

    return $new;
}, 10, 2 );

And here’s the CSS code:

/* Estilos para la miniatura en la tabla de agrupados */
.woocommerce .woocommerce-grouped-product-list .grouped-label-with-thumb{
  display:flex; align-items:center; gap:12px;
}
.woocommerce .woocommerce-grouped-product-list .grouped-thumb{
  width:48px; height:auto; border-radius:6px; display:block;
}
@media (min-width: 768px){
  .woocommerce .woocommerce-grouped-product-list .grouped-thumb{ width:56px; }
}

I hope this will be helpful for anyone who might need it in the future.
Best regards!
