product image showing too large

i have {{cart.product.table}} in my email to show the products, i have set the display image to true in the email template file, however the image is showing up very large. i have tried to change this but it is not taking effect. Can you help with this please?

This is how i have the current template, changing the image size doesn’t seem to have any effect

` <?php
echo wc_get_email_order_items( // phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped
$order,
array(
‘show_sku’ => $sent_to_admin,
‘show_image’ => true,
‘image_size’ => array( 2, 2 ),
‘plain_text’ => $plain_text,
‘sent_to_admin’ => $sent_to_admin,
)
);
?>
