Woocommerce Image Size – Product Image and Thumbnails

Hi,

I am having trouble with the image size and I am hoping you can help. See this example: Link Here

The product image is all blurry and upon checking the source code, I can see that it is the same size as the thumbnail 120×120. I have configured the product image to be 300×300 but for some reason it keeps on loading a thumbnail size image. The image is much bigger than that so the original image size is not the problem.

I am using the Regen Thumbnails plugin but perhaps this is not configured properly. Kindly assist.

Thank you
