2. 7.3 uc_product/uc_product.module \uc_product_add_default_image_field()

Creates a file field with an image field widget, and attach it to products.

This field is used by default on the product page, as well as on the cart and catalog pages to represent the products they list. Instances are added to new product classes, and other node types that claim product-ness should call this function for themselves.

Parameters

$type: The content type to which the image field is to be attached. This may be a a single type as a string, or an array of types. If NULL, all product types get an instance of the field.
