Hi!
The issue is that you’ve got two copies of widgets-js being included in your page, one very old copy which has been copied locally into your page and is referenced in the <head> (/js/widgets.js), and the other which is referencing our server in the timeline embed code itself.
The way we detect that widgets have been initialized changed in an update so both scripts are instantiating a copy of the timeline simultaneously (one of them doesn’t support all the new features, hence the missing images.)
You can fix this by removing your local copy of widgets from your template.
Thanks,
Ben
