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.

I want to put some youtube’s video in a lightbox, by clicking on thumbnails of this carousel flash/xml menu.

How could I do that?

Unfortunately Lightbox can’t be used to stream videos from Youtube. Theoretically you could use MediaBox to stream videos from youtube.

In images.xml you need to set the value _self for target attribute.

I’m using Image Scroller FX , it works fine when i see it in firefox but not in iexplorer . I’ve another flash animation in the top of the web page. The lightbox is Under the animation but not in firefox. There is a site for test:

Also i want to aling to the topof the scroller the images, all of them have the same width but not height

any advice ?

Thanks for your atention.

FlashXML Support


The Image Scroller FX makes a best fit for the images. Edit settings.xml and change the value of the attribute thumbWidth, in your case with the present settings, set the value to “300”.

<thumbWidth value="300"/>

I LOVE this feature. I have used it on my portfolio websites since day 1. I just finished putting it in my backend site… It works great in Firefox, Safari and Opera… and they all work great… but when I get on my PC and look up the site with IE, the lightbox seems to pop up behind the swf file.. If you would like to see what I mean go to the website.. click home… and click the first box in the right side of the screen (it should have my old graphic design website name “KOKEAR” displayed)... If you look at it in Internet Explorer you should see the problem. If you have the time, please let me know what I need to change. I am sure it is probably easy but it is now 11 at night and I have been up working on websites for the past 3 days… Any help is greatly appreciated.

Lightbox is not a feature developed by us and this tutorial is about how to use lightbox for our components, but I can suggest you to increase the value of z-index for lightbox in the lightbox.css file.
