Lightbox is small javascript library used to overlay images on top of the current page. It's a snap to setup and works on all modern browsers.
			Lightbox2 is open-source.
View and fork the code on Github.
		 
js folder to find 
  jquery-1.10.2.min.js and lightbox-2.6.min.js and 
  load both of these files from your html page. Load jQuery first: 
<script src="js/jquery-1.10.2.min.js"></script>
<script src="js/lightbox-2.6.min.js"></script>
css folder to find lightbox.css 
  and load it from your html page: 
<link href="css/lightbox.css" rel="stylesheet" />
img folder to find close.png, 
  loading.gif, prev.png, and next.png. 
  These files are used in lightbox.css. By default, 
  lightbox.css will look for these images in a folder called 
  img.data-lightbox attribute to any image link to activate 
  Lightbox. For the value of the attribute, use a unique name for each image. 
  For example: 
<a href="img/image-1.jpg" data-lightbox="image-1" title="My caption">image #1</a>
title attribute 
  if you want to show a caption.data-lightbox attribute value for all of the 
  images. For example: 
<a href="img/image-2.jpg" data-lightbox="roadtrip">image #2</a>
<a href="img/image-3.jpg" data-lightbox="roadtrip">image #3</a>
<a href="img/image-4.jpg" data-lightbox="roadtrip">image #4</a>
rel="lightbox". The new 
  data-lightbox approach is preferred though as it is valid 
  html.If you find a bug, create an issue on Github. Include your operating system and browser version along with detailed steps to reproduce the bug.
