This contribution will give you the ability to have multiple images per product.
There are several contributions available that allow you to have different size
images, or multiple images, but none of them seemed to work for my needs. So I
created my own version which has no limit on the amount of images you can add.
The way this contribution works is very simple, it keeps extra images in a new
table in the database. Each product can have the 1 main image (in the products table) as
well as an unlimited number of images from the new extra_images table.
Includes admin interface for adding images to each product, also has 2 options for how the images will be displayed.
