Latest Update:
WC has an update that has fixed the missing product images…however, now some (random) pictures are pulling from a smaller thumbnail size and making the feature product image very blurry. When clicked to view lightbox, they are linked to the original size, 600px × 575px, and are perfectly clear. Anyone else run into this?
The CSS from @efquintana works for a temporary fix, but the images do not appear how they should with WC. (thanks efquintana!!)
I am using Enfold which was working with WC before the update.
