How to add images to WooCommerce order email

When a new order is placed in WooCommerce, customer receives an email with order items. But it does not include product images. We can add product images to order email using woocommerce_email_order_items_args filter. We can also control the image sizes to display on the email.

function careless_add_images_to_wc_emails( $args ) {
    $args['show_image'] = true;
    
    return $args;
}
add_filter( 'woocommerce_email_order_items_args', 'careless_add_images_to_wc_emails' );

Above code will display product images in order emails. Default image size is 32×32 pixels. If you want a different image size, we can use image_size array key to define our custom size.

function careless_add_images_to_wc_emails( $args ) {
    $args['show_image'] = true;
    $args['image_size'] = array( 100, 50 );
    
    return $args;
}
add_filter( 'woocommerce_email_order_items_args', 'careless_add_images_to_wc_emails' );

Code goes in the functions.php file of your active theme.
