A customer can have a set of digital photographs in his desktop which he/she wants to print. He/she can provide the application the path to the folder where the photographs are stored and can choose the photos that he/she wants to print and choose the size of the prints. The application will calculate the price after downloading the price information from the database for the different print sizes and show it to the user. The user will enter his/her credit card/other payment option (or choose any other mode of payment) and shipping information if he/she wants to go ahead with the order. If the credit card information is found correct, the photos are uploaded to the server and a purchase order is created in the database.
