你不能和woocommerce_get_product_thumbnail(), 但这会给你完全相同的结果：

global $product;

$image_size = apply_filters( \'single_product_archive_thumbnail_size\', \'woocommerce_thumbnail\' );
$custom_alt = \'Put your custom alt text here.\';

return $product ? $product->get_image( $image_size, [ \'alt\' => $custom_alt ] ) : \'\';
