Hi I would like to know how I can make it so that a person uploads a picture as an option and then also have a option to select how many they want to purchase of the product instead of readding it to cart one after another. I also want to be able to show them the picture they uploaded on the checkout_confirmation page and preview it right after they upload the picture. I'm making a shirt business where someone can upload a logo/pic to put on a shirt and buy quantities of it. Any help on how I can achieve the effect I want would be glady appreciated.
