I find only one way to allow user do download image / view image as file in browser - action on click. But this action disables all other possible actions on click - next image, close - an the click on image ia the main way to interact with it.
Is there any way to add link to image/download image in caption, signature, anywhere?
It seems that there only two options now
1. Completely block downloading of images
2. Make viewing very uncomfortable with downloading on click instead of next image (close etc)
So sad becase all other functionality is brilliant.
