Thumbnails on final Checkout Page

Not sure if this a Symbiostock issue or Woocommerce or my theme, but thought I would ask…

On the Cart page after adding a product there is a column that shows the image thumbnail.

But on the final checkout page (https://www.microstockman.com/checkout/ – you will have to add a product to cart) no thumbnail appears in a column, which would be useful for the customer to confirm before paying.

Is this a Symbiostock thing, or theme related?

Thanks
