Icons not appearing in DIVI gallery

Hello, this is such a great plugin, and I have nearly managed to get it all working, but I’m just running into a couple of strange glitches that I can’t work out.

I am placing an email icon on all images using the following javascript code for testing:

a2a_config.overlays.push({
 showOn: 'visible',
 useImage: true,
 services: [ 'email', ],
 target: 'img',
});

It works fine for every image except gallery images with a landscape orientation. It just won’t appear on those images.

I’ve tried loads of different classes, but just can’t get it to work.

The other problem is that the icon on the popup lightbox image breaks the lightbox after first click. The following images don’t appear on the page.

The webpage link: https://bloodystuff.infinityfreeapp.com/ has two of the same gallery on it – one portrait and one landscape. The icon appears fine on the portrait one (but the lightbox is broken).

I have tested it out on two different websites with the same results.

Any help would be much appreciated!

Many thanks,
Ian
