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.

Hi, I have carousel and lightbox up and running on my joomla website but it seems to have broken my top menu. I have carousel load on the “Rental” page under Contact Us. I move my mouse over contact us, the submenu will show but when I moved towards the rental tab, the tab goes away. I believe I have troubleshot it down to this script

<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>

When I rem out the line with js/prototype.js the menu problem goes away, but my carousel stops working.

Sounds like the prototype.js code is conflicting with the menu code that you have integrated in the site. Lightbox is an open source code, and you could ask their developers why this conflict appears.
Alternatively you could try to implement other scripts to your page, that have the same effect, like Fancybox

- – To “hide” the previous and next buttons, just the delete the .GIF files in the js/css folder (next, nextlabel, prev or prevlabel). Then they will then not appear in Lightbox anymore. – -

I’m using both the GroupDelegate and the LightboxDelegate scripts, so how can i disable the prev/next for only LightboxDelegate?

- – Concerning your second question, I couldn’t tell which FX component you are referring to, could you please specify? – -

I’m using Lightbox++1.0.1, same version available here for download. Not sure why the image set doesn’t loop back when you reach the end.

FlashXML Support


If you want to open just one picture, please follow step 4B, this automatically tells Lightbox to not open the prev/next buttons, as it only loads one picture. Concerning the second question, the component doesn’t have this functionality implemented. You will have to contact the Lightbox development team for further details.

Is there a way to disable the next/prev buttons when a single image is displayed? Also is there an issue with the image sets not returning to the first image when it reaches the last one?

Hey there, thank you so much. It apparently doesn’t work in Google Chrome and Safari on Mac (I have yet to see it in Windows). It does however work if you click outside of the box.

This won’t be an issue then, I can just change the graphic or something to say “click outside to close” or something to that nature.

Thank you very much for your help AND for teaching us how to add Lightbox to Flash. Words can’t express how much I am grateful.
