Solved: "Gallery images faded until scroll"

Dude’s solution works but modifying the core theme code has a risk of being overwritten by updates. I recommend creating a child theme to make your modifications. You can access the function from there.

// Add this to an enqueued JS file in your child theme
(function($){
var gallery = $(‘.avia-gallery’).avia_sc_gallery();
gallery.trigger(‘avia_start_animation’);
})(jQuery);
