About Fullscreen Lightbox
We want to bind multiple Fullscreen Lightbox in one page as a result we are having a problem that it is counting more pictures than in that particular section i.e. It is counting total pictures of every Fullscreen Lightbox. Example we are having 4 Fullscreen Lightbox on our page each having 2 images than it is counting as 8 images in total like 1/8.
Please check the plugin's integration documentation here and see working examples of lightbox image groups. There are a few lightbox instances with multiple images per instance.
For more info please refer to the Plugin's official docs.
