With reference to the WooCommerce Photography extension and recommended addon plugin Easy Watermark.

After purchase the client ONLY gets access to download a watermarked image. The non-watermarked image is not stored or available in the DOWNLOAD section of the client's account.

This means that non watermarked images will need to be manually sent to the client after purchase.

I am looking for the functionality to send purchased Non Watermarked images to the client via the download link on their account page.
