PhotoPress – PayPal Shopping Cart is a WordPress plugin by padams that allows you to add shopping cart functionality to single image (attachment) pages so that visitors can order prints or other merchandise of any image on your website.
Specifically designed for photographers who want to enable print ordering for large image catalogs, this plugin utilizes the WordPress Simple Paypal Shopping Cart plugin to implement the shopping cart and accept payments via Paypal. The title of the Image/Page/post is dynamically used as the product name so there is no need to setup and maintain a parallel e-commerce “product catalog” like most other plugins require.
The plugin also provides a widget, shortcode, and template functions for displaying the shopping cart on single image (attachment) pages, single Posts, and Pages.
