Brian,
I guess this is out side the scope of ACF. However, one strategy (that might work) could be:
1. Hide your images with css:
#gallery-1 { display:none;}
2. Create a button “Photos”
3. Add a jQuery click event listener to the button that performs/fakes a “Click” on the first image – to start the Simple Lightbox:
jQuery(document).ready(function($) {
// cache variables -Id #btn-photos is generic - chang with your own actual ID or Class
var btnPhotos = $("#btn-photos"),
galleryItems = $("#gallery-1").find(".gallery-item a");
$("#btn-photos").click(function(event) {
// something like this MIGHT work..
galleryItems.first().click();
});
});
Might be better ways, but this is first that came to mind.
Regards!
