I'll have a look at that in a moment and report back .

One other question. In the shopping cart it displays the image assigned to the attribute for the selected variant. Unless I missed it in admin somewhere, I don't see any way to override this as an option. The site where SBA is being used has icons to represent different strengths of a product, so having this display as the product image in cart is not a desirable option in this use case.
If it's not admin switchable, can you point me to the file where this is controlled so I can modify the behaviour? Perhaps add it as a configurable option if not already.
