How to use Lightbox with a flash component

Follow these steps to add Lightbox (possibility to pop-up only images) functionality to Flash files:


Step 1. First, download Lightbox++

Step 2. Copy the css, images and js folders from the archive in the same folder with your HTML file on your web server. This HTML file should embed the SWF file to which you want to add the Lightbox to.

If your site is running on Wordpress or Joomla, you will need to copy these folders in a new folder, let's call it lightbox, in the root of your Joomla/Wordpress site.


Step 3. Edit the HTML file and add these lines in the <head> section:

<link rel="stylesheet" href="css/lightbox.css" type="text/css" media="screen" />
<script src="js/prototype.js" type="text/javascript"></script>
<script src="js/scriptaculous.js?load=effects" type="text/javascript"></script>
<script src="js/lightbox++.js" type="text/javascript"></script>

Make sure you use the correct path for the above files.

For Joomla or Wordpress sites, you need to update the code, to make it point to the root lightbox folder, where you copied the Lightbox folders in step 2:

<link rel="stylesheet" href="lightbox/css/lightbox.css" type="text/css" media="screen" />
<script src="lightbox/js/prototype.js" type="text/javascript"></script>
<script src="lightbox/js/scriptaculous.js?load=effects" type="text/javascript"></script>
<script src="lightbox/js/lightbox++.js" type="text/javascript"></script>

If your site is running on Joomla, you will need to add the code right before the </head> tag of the index.php file located in your active template's folder (e.g. templates/rhuk_milkyway/index.php)

If your site is running on Wordpress you need to add the code in the <head> section of the header.php file located in your active theme's folder (e.g. wp-content/themes/twentyten/header.php)


Step 4 (option A). If you want to have a Lightbox Image Set (with Next and Previous buttons), right after the lines from Step 3 add these lines, otherwise go to Step 4 (option B)

<script type="text/javascript">
function GroupDelegate(id) {
 var objLink = document.getElementById(id);


In the body of your HTML file you’ll have to add invisible links to the images which will be displayed in the Lightbox, like this:

<a id="img1" title="First image" rel="lightbox[img]" href="images/01.jpg"></a>
<a id="img2" title="Second image" rel="lightbox[img]" href="images/02.jpg"></a>


Step 4 (option B). If you intend to have a single image display in Lightbox (as opposed to option A with Image set) you simply have to add these lines into the <head> section of the HTML file:

<script type="text/javascript">
function LightboxDelegate(url,caption) {
 var objLink = document.createElement('a');


Step 5 (option A). If you’re using SWFObject to embed the SWF, make sure you’re having these two params (in addition to maybe other params):

params.wmode = "transparent";
params.allowscriptaccess = "samedomain";


Step 5 (option B). If you’re using <object> </object> tags to embed the SWF file, add these lines:

<param name="allowscriptaccess" value="samedomain">  
<param name="wmode" value="transparent">

And in the embed tag you must insert the attribute:



Step 6. If the links to go to when clicking an image are specified through the XML file, the url attribute, or in some cases the link attribute, must be set like this:
1. For Step 4 (option A):


2. For Step 4 (option B):

url="javascript:LightboxDelegate('images/01.jpg','First Image')"

Also, you’ll have to change the target attribute to _self like this:



Note that the Lightbox will not work if tested locally. You’ll have to test it on a HTTP server.

Make sure that you set the target to _self.


navigateToURL(new URLRequest(“javascript:LightboxDelegate(‘images/01.jpg’,‘First Image’)”), "_self"); 

This way it should work.

I’m trying to add Lightbox functionality to the Image Scroller FX in my site using Wordpress. I’m not having much luck.

I’ve followed the steps as best as I can, omitting step 5 as I saw in a previous comment to do so.

I’m using Lightbox2 as I saw in the original post on you could use any Lightbox script based on Lokesh Dhakars one.

I really don’t know where I’ve gone wrong. Please could you help? Here is my link: http://clairefrost/career/coverage
