Hello Russell,
Thanks for reaching out with your question. I’m sorry you are having an issue with the photo view and the shortcode. Let’s try to get to the bottom of this.
I checked your photo view page (http://www.todovictoria.org/events/photo/) and I saw a JSON error coming from here: wp-content/plugins/css-hero-animator/assets/animator-applier.js
CSS hero animator might be causing an issue on that site.
What I see on the shortcode that you pasted, that it has curly quotations marks. These can cause errors and it is recommended to use the straight quotes instead. ( “” good vs. ”” bad)
Also I would recommend you to run a full test for conflicts to see if there is any other plugin or the theme that could be causing an issue here.
Let me know what you find, then we’ll go further from there.
Thanks and cheers,
Andras
