Hi, Frank.
I understand your issue, but such customization is outsideĀ our Scope of Support / Terms.
That being said, my guess is that Line 133 (or one like it) of /wp-content/plugins/events-calendar-pro/src/resources/js/tribe-events-photo-view.js is at play here:
$( '#tribe-events' ).on( 'click', 'li.tribe-events-nav-next a',function( e ) {
Note that the minified version of this file will load unless you have define( 'SCRIPT_DEBUG', true ); in your wp-config.php file.
Even still, I’m not sure how to advise you to customize this as you’re wanting.
Please let me know what you find out.
