AbleCommerce Shopping Cart Software

I'm using variants to track a product. The product is a gift bag which comes in two sizes (large, small). I have that all working but I did notice when you purchase one of each size and view your cart, only the image for the "large" shows for both the large and small. Is there an "easy" way to fix this so the large shows the image for the large size and the small shows the image for the small size?

Thanks!
