Justified Image Gallery not work with Facebook.
I try share one (my own) page: https://elkesan.fi/elkesan-langattomat-ovipuhelimet/ in facebook. Facebook cannot download preview image. Typically, when you share any link in facebook, any photo appear.
Inside this page is simply images: [justified_image_grid ids=1480] etc.
So, look JIG is not “compatible” with facebook. How I can fix this problem?
