Jigoshop theme error for large images on product page

Q: When you go to Jigoshop > Settings > Images and set the large image down to smaller, the image is reduced in size but then scaled back up to the original size on the product page. In other words, setting the large image size has no effect any more on the display of the image.

A: This is due to CSS. Add this to the bottom of your style.css file:

div.product div.images a img {
    width: auto !important;
    height: auto !important;
