将上一个/下一个按钮添加到图库？

I am using the latest version of the "jQuery lightGallery" plugin. I want to add a previous/next button to show the previous/next image in the carousel. I can't find any documentation about this, so maybe someone here does know how to to that?

And now, Here is your JS:

现在,这是你的JS:

$(function() {
    $("#thumbs").find(".thumb:first").addClass("active");
    $("#large").find(".bigthumb:first").addClass("active");
    var getIndex = $("#thumbs").find(".active").index();    
    $(".controls").each(function() {
        $(this).find(".next").click(function() {
            getIndex = $("#thumbs").find(".active").index();
            getIndex += 1;
            if (getIndex > ($("#thumbs").find(".thumb").length - 1)) {
                getIndex = 0;
            }
            setActiveImage(getIndex);
        });
        $(this).find(".prev").click(function() {
            getIndex -= 1;
            if (getIndex < 0) {
                getIndex = $("#thumbs").find(".thumb").length - 1;
            }
            setActiveImage(getIndex); //Set/Show Active Image
        });
    });

});
function setActiveImage(index) {
    if (typeof(index) == "undefined" || index == "" || index == null) index = 0;

    $("#thumbs").find(".thumb").removeClass("active");
    $("#thumbs").find(".thumb:eq(" + index + ")").addClass("active");
    $("#large").find(".bigthumb").removeClass("active");
    $("#large").find(".bigthumb:eq(" + index + ")").addClass("active");
}
