Why does Checkout in Preview Mode not have thumbnails?

Stripe checkout uses full LIVE URLs to the images to display at checkout. Since the images in RapidWeaver PREVIEW mode are only available locally, Stripe has no way of accessing them. Once the project is published on a LIVE server, then the thumbnail images will be visible at checkout.

P.S. PayPal does not have support for product images regardless of PREVIEW or LIVE access.
