I have a wine store and want to use the Basel theme for my wine shop. The problem I have is with the Imagesize of the thumbnails as well as the image size on each product page. As wine bottles tend to be longer than wide I need more elongated pictures. But what happens is that it either displays only a square thumbnail with only a partial view of the product or on the product size an almost life size picture which is way to big. Ho do I set standard image sizes for thumbnails and product pictures with more hight than width.
