Why are my WooCommerce product images not updated on Amazon?
The reason is that imported and matched items don’t have a listing profile assigned by default, so WP-Lister uses the generic (not category specific) ListingLoader feed template, which only contains basic inventory information like quantity, price and condition but no columns for images.
To include product specific details like images, bullet points and category specific product attributes in your feeds, you need to assign a listing profile to your imported products. Select the appropriate feed template for your products and set it up as if you were listing new products on Amazon.
Product images don’t appear in the profile editor, because they are handled internally by WP-Lister. But only the category specific feed template can have information about product images – the generic Listing Loader template does not have these columns.
