When creating new listings on Amazon from Linnworks how do I use swatch images?
Use Extended property AMAZON_SWATCH_IMAGE to specify a swatch image.
You can have the same image URL for product image and swatch image, but file extension for the swatch image must be written in capital letters. In this case system will treat them as two different URLs.
AMAZON_SWATCH_IMAGE only works when creating new listings. If the item is already listed, you will not be able to add swatch images to the listing.
Listings created in the Amazon categories that support swatch images will be created with a swatch image
