New product images from media gallery don't show after update

WPEC Version 3.8.13.4
Function added to show multiple product images, which worked fine for years. If I upload them new they show up, but when inserted from media gallery they don’t.
single_product.php was moved to the theme directory, but I checked it to make sure it’s the same as the new version.
Stumped…..
