The SKU ties are a fine way to match images to listings easily, but it could be much more powerful and useful. Two ideas come to mind - Allow Tags for images as an option to import images into listings; allow matching partial SKUs, such that if my SKUs are 1234-5678 and 1234-8765, where 1234 indicates to me it is clothing, an image with SKU 1234 would match both of them. I would think match full SKU, partial SKU, and match Tags would be 3 different check boxes when you initiate the import.
