Bootstrap Lightbox：顯示來自title屬性的圖片字幕

Question

Javascript和jQuery仍然非常新穎，所以這對我來說很難。

我使用這個引導燈箱插件：https://github.com/duncanmcdougall/Responsive-Lightbox

嘗試使用在這個網站上（WIP）：http://lastdetailwd.com/modernmetalfabricators/furniture.html

我期待使用來自該title屬性此燈箱的標籤爲標題。有關如何完成此任務的任何線索？

jQuery的：

(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();

     resizeImage: function() { 
      var ratio, wHeight, wWidth, iHeight, iWidth; 
      wHeight = $(window).height() - opts.margin; 
      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;
