I know the documentation says that the plugin can't do it, but is there any possibility of hacking the plugin to use "Add to Cart" instead of "Buy Now".
Background: this is for clients to purchase photographs of their wedding (and over events). Having them buy one photo at a time isn't going to work, we need to be able to add them to a cart. And having to add a product for every single event (~500-600 images) would be too time consuming to manage manually.
Aside from that caveat, the plugin will work perfectly for what we want.
Any advice here?
