I found a working proof of concept for the original non-WP PhotoSwipe gallery that I need so it should just be a matter of adapting the solution to the wordpress plugin, right?
I’ve been hacking away at that for some time, trying to adapt the initialization code iinto header.php to get the same result but so far without luck.
I’m hoping someone more capable might be able to find the way. And thank you, btw, to whomever if you care to help out on this.
