Create WooCommerce product dynamically - on click.

Hello! I have a client who needs every image in every gallery to be purchasable and downloadable. See the galleries here: [login to view URL] I have attempted to create a solution but I have a limited knowledge of Wordpress. When a user clicks on an image, the image needs to be added to the cart along with the variable download link (depending on the image clicked). I hope this makes sense! The user will then be able to go through the WooCommerce checkout as normal. I believe this code: [login to view URL] can be of use in this solution, a generic product could be added to the cart with only the download link being changed to whatever image was clicked. There are thousands of images that are uploaded to this site every week so uploading each image as a product individually in WooCommerce is NOT an option! Hence why this solutions needs to be created. Thanks for looking and I hope someone can get this done! I will require details of the solution before I award the project.
