This works great! Thanx
But I’m afraid I have to disable the plugin, because recently I’ve found out: on the first load (when the images are not cached) the wp-lazy-load addon doesn’t work and images get overlapped at the end of the page. This happends in the newest Firefox version and probably has something to do with this masonry layout script from here: https://masonry.desandro.com/
If you have an idea, how to fix it, I would highly appreciate it.

If you don’t have time to look into it, please let me know, because than I sadly have to disable the plugin for now.
