Use stopPropagation() when user clicks over an image, otherwise capture the click event on the body (or other element) and remove the selectedd class on the image (if any)

$(function(){
    var ff;

    $('.ddd').on('click', function(evt) {
        ff = $(this);
        evt.stopPropagation();
        $('.ddd').removeClass('selectedd')
        ff.addClass('selectedd')
    }); 
    $('body').on('click', function() {
        if (ff.length) {
           ff.removeClass('selectedd')
        }
    });
});
