Divi Accessibility

I’m struggling to get ALT text to show on custom Woo product pages built with the Divi Theme Builder. Someone there Alex Stine made a cool Accessbility plugin for Divi that is in the public repo. It doesn’t fix this problem. Maybe he could help?
You can see it on the main product image here…
