commenting

No not really. I would use single posts for comments or are you after comments on single images?

just like jetpack carousel do, I suppose they use the wordpress single image commenting system with ajax…

OK that would be a lot of work to implement. I don’t plan on adding that sorry.

OK thanks !… very few lightbox are offering that option you know…

Could you give me a hand, just to have a share button like FB/Twitter etc with the link to https://www.mywebsite.com/image-name, in order to comment it like a single post ? I could make the button but I’m missing to generate the url in javascript. Many thanks…

That would also be a bit tricky to setup. You might need a developer to work on that custom code for you.
