[Plugin: WooCommerce] Blurry images

Hello,
No matter what I do I cannot get the product images for this site to be crisp. I have uploaded my own images thinking the images my client uploaded were not appropriately sized, and still a no-go.
Here is the site:
http://globalmomproject.com/shop/
The funny thing is this client has another site she is using WooCommerce on, and her images are fine. I noticed she has a featured image area in her products where she has uploaded her product image, and on the new site I don’t have that.
Here is the link to her other site:
http://bepresentproject.com/shop-2/
Any help would be greatly appreciated!
Thanks!
Elaine
