Good evening DAVID and welcome back!
Thank you for reaching out to us.
Just to set expectations, as you might know, the scope of our support is mostly to get our customers started on the right track and to help them in case of issues. We unfortunately do not provide complete support for customizations.
With that in mind, if you haven’t already, you might want to read our Themer’s guide to get a good sense of how to get the info you are missing.
More specifically, I would scour the following directory: /wp-content/plugins/events-calendar-pro/src/views/pro/photo
Among other things, you’ll notice that you require the following class “tribe-events-photo”.
Let me know how that goes.
Best regards,
Geoff B.
