Bootstrap Lightbox：显示title属性的图像标题

Question

Javascript和jQuery仍然很新，所以这个对我来说很难。

我正在使用这个Bootstrap Lightbox插件： https://github.com/duncanmcdougall/Responsive-Lightbox

尝试在此网站（WIP）上使用它： http://lastdetailwd.com/modernmetalfabricators/furniture.html

我希望将此灯箱的A标签中的标题属性用作字幕。关于如何完成这项工作的任何线索？

的jQuery ：

(function ($) {

'use strict';

$.fn.lightbox = function (options) {

    var opts = {
        margin: 50,
        nav: true,
        blur: true,
        minSize: 0
    };

    var plugin = {

        items: [],
        lightbox: null,
        image: null,
        current: null,
        locked: false,
        selector: "#lightbox",

        init: function (items) {
            plugin.items = items;
            plugin.selector = "lightbox-"+Math.random().toString().replace('.','');

            if (!plugin.lightbox) {
                $('body').append(
                  '<div id="lightbox" class='+plugin.selector+' style="display:none;">'+
                  '<a href="#" class="lightbox-close lightbox-button"></a>' +
                  '<div class="lightbox-nav">'+
                  '<a href="#" class="lightbox-previous lightbox-button"></a>' +
                  '<a href="#" class="lightbox-next lightbox-button"></a>' +
                  '</div>' +
                  '</div>'
                );

                plugin.lightbox = $("."+plugin.selector);
            }

            if (plugin.items.length > 1 && opts.nav) {
                $('.lightbox-nav', plugin.lightbox).show();
            } else {
                $('.lightbox-nav', plugin.lightbox).hide();
            }

            plugin.bindEvents();

        },

        loadImage: function () {
            if(opts.blur) {
                $("body").addClass("blurred");
            }
            $("img", plugin.lightbox).remove();
            plugin.lightbox.fadeIn('fast').append('<span class="lightbox-loading"></span>');

            var img = $('<img src="' + $(plugin.current).attr('href') + '" draggable="false">');

            $(img).load(function () {
                $('.lightbox-loading').remove();
                plugin.lightbox.append(img);
                plugin.image = $("img", plugin.lightbox).hide();
                plugin.resizeImage();
            });
        },

        resizeImage: function () {
            var ratio, wHeight, wWidth, iHeight, iWidth;

            wWidth = $(window).outerWidth(true) - opts.margin;
            plugin.image.width('').height('');
            iHeight = plugin.image.height();
            iWidth = plugin.image.width();
            if (iWidth > wWidth) {
                ratio = wWidth / iWidth;
                iWidth = wWidth;
                iHeight = Math.round(iHeight * ratio);
            }
            if (iHeight > wHeight) {
                ratio = wHeight / iHeight;
                iHeight = wHeight;
                iWidth = Math.round(iWidth * ratio);
            }

            plugin.image.width(iWidth).height(iHeight).css({
                    'top': ($(window).height() - plugin.image.outerHeight()) / 2 + 'px',
