love it UPDATE: now even more…

Great plugin, easy to use and customize, great SEO options. Big thanks to the developers.

My only note: it would be very handy, if the images in a gallery could be replaced later with another one if needed without losing all the already attached parameters (caption seo etc.).

UPDATE

I had to come back to tell you: they did it! The replace option is there, and much more.
The team added another great feature: you can now customize the galleries for social share. If you’ve ever tried to prevent users from pinning your thumbnail pictures without restricting the sharing of the original-sized images, you will appreciate this option. You can set each gallery as you wish.
You have to download their Social Share plugin to use it, but it’s a great plugin anyway, just as easy to customize as the gallery plugin, with lots of options.

Their support team is also excellent: quick, professional, helpful.
Thank you very much!
