Not just you, it's doing it for me also.

Probably caused by:

    (function($) {
        $(document).bind('contextmenu dragstart', function(event) {
            var target = event.target || event.srcElement;
            target = $(target);
            if (target.data('ngg-protect') || target.parent('a').data('ngg-protect') || target.attr('id') == 'fancybox-img' || target.attr('id') == 'TB_Image' || target.attr('id') == 'shTopImg' || target.attr('id') == 'lightbox-image' || target.hasClass('highslide-image') || target.parents('.ngg-albumoverview').length == 1 || target.parents('.ngg-pro-album').length == 1 || photocrati_image_protection_global.enabled == '1') {
                event.preventDefault()
            }
        })
    }(jQuery));

It's extremely annoying when sites do this...

It's JS hate that needs to die. Maybe there's a name for a condition where people are so stuck up in their ways they can't accept objectively positive change (of The web platform).

As for this bs code, the people who wrote this will find other ways to discredit themselves, it's not a job of a platform's maker to babysit everyone and prevent their stupid decisions.

Be thankful that you can actually override this due to platform's (and JS's) openness, it could've been far worse, in many other cases you'd need disassembly to fix something like that.
