I am trying to sell prints as well as downloadable files. When the prints are enabled in the admin, and you try to purchase the prints, the shopping cart adds other files when adding to cart. Is there a fix for this?

Random images attatch to shopping cart when adding "Prints" to the cart.
shopping cart php files This may be the problem. Can you see if you can fix this?

Also when random images are added you cannot delete them from the cart. Trying to delete them will also delete the print you added to cart.

Thank you
