Why my products' thumbnails haven’t been migrated to Shopware?
Products’ thumbnails are not migrated by default to Shopware. Therefore, you have to generate them with the help of the Thumbnail Generator in Showare 5. It allows creating thumbnails of your original pictures in sizes you are able to configure beforehand.
To generate thumbnails in Showare 6, visit Thumbnail Settings in your admin panel and activate the thumbnail generation for the required products.
