You can now sync your Product Catalog images to your market listings. This allows you to manage your images across all marketplaces from one place.
This can be done from the Product Catalog page or the Edit Market Listing page. When you select to sync from the Edit Market Listing page it only applies to the listing on that channel.
When you choose to sync from the Product Catalog page it syncs all market listings attached to that product.
Be aware that syncing images from Product Catalog will permanently replace your local images for that listing.
