Members using custom sites now have more options for setting up products - instead of manually specifying cropping for various sizes, there is an Auto Product Setup button that will match up your image's aspect ratio with paper sizes and set up the products for you.
You can also set up your own default pricing which will be applied to these auto-created products, and can be applied to existing products as well!
