Hello @atelierdevs,

For adding a thumbnail of the product image next to the title of all the products, please add the below code in your active theme’s functions.php file or using a plugin like Code Snippets:

function add_product_image( $product_name, $item ) {
	$product_id    = $item['product_id'];
	$product_image = wp_get_attachment_image_src( get_post_thumbnail_id( $product_id ) );
	?>
	<img src="<?php echo esc_url( $product_image[0] ); ?>" width="50" height="50" >
	<?php
	echo $product_name;
} add_filter( 'wcdn_order_item_name', 'add_product_image', 10, 2 );

Regards,
Moksha.
