"Single image" example on demo page does not open

[Mesoptier]

Tested in a bunch of common browsers (Chrome 56, Firefox 51, IE 11, etc.). I can see some classes/styles being added, but the images does not move to a fullscreen overlay.

Seems like the link is broken due to accidental insertion of two ss characters. Fixed in 0698be5.
