This allows for the display of product options/attributes as a list of images with radio buttons instead of drop-down select lists. This can be turned on/off in admin.
Additional option of making the thumbnail option images clickable to a larger image in another window (for getting a good look at fabrics, wood grains etc.).
This also incorporates some changes to the admin side of product attributes and new product/product edit.
Options can be created in groups and sub-groups. Attributes can be added to a product on the product admin page by selecting entire groups/sub-groups of options, and then cutting the list down even further, and adding appropriate prices, on the product preview page.
