Can this be selectively disabled?

Yes! I need this too. A shortcode that would opt the page/post it’s on out of using this feature would be ideal. I have one image on a page that needs to be an image map that links to another page and it’s impossible to do this with Gallery Share turned on. Instead a blank lightbox pops up and nothing goes anywhere. I don’t want to use the selective feature because i have thousands of images that I DO want to be shareable.
