Shopware 6 - Multiple Images and Variant Images how to get?

Question

1. Some Products has multiple "main" images. But I see only one if I check the product with the API endpoint store-api/product/productid, is there a different endpoint for checking images ?

2. I need the image from "Citrus-Quark", but there is no mediaId or media, but it has a different image in the frontend. How can I get it then?

The Shopware 6 store-api docu is a little slim.
