In single product page thumbnails below main image are cutted to square by default. But why? Our models heads are cutted off in this way and this is not nice. Let's do it like before: thumbnails height is not fixed. (size is not always 100x100 px but 100x120 for example, same proportion like in main image.) I know it is possible to set up this if you are programmer, but there must be some easy way to do this.
