I am having fun implementing the Lightbox javascript effects on images on my Moodle site. It was just yesterday that I realised that I could upload image files into a Moodle folder resource, but when I clicked on an image file, the file downloaded instead of loading up on-screen. It was then that I decided to see if I could make a clicked file link open up on-screen with the Lightbox effect. I am happy to say that I have succeeded to do so, albeit with a hack or two.

Here is my Moodle folder resource.

Nothing out of the ordinary here....

Whoa! It's a lightbox image effect. Click the 'x' to close.

Lightbox is a JavaScript library that displays images and videos by filling the screen, and dimming out the rest of the web page. The original JavaScript library was written by Lokesh Dhakar. The term Lightbox may also refer to other similar JavaScript libraries. Text is from: Lightbox (JavaScript) - Wikipedia, the free encyclopedia

In this post, I will show you how you can enable Lightbox for an image hyperlink in a Label resource on your Moodle site. The genesis of this post was the Blog Learning Rocks. Dan Roddy has written an average of one blog post a year for the last two years, and seven posts a year for the last six years. Which is not much, but this 2010 post of his has become my inspiration for today's post. In fact, thanks to Dan's post, I've also managed to enable the Lightbox effect on image files inside a Moodle folder resource! More on that later in another post on Moodurian.

Well, let's get started shall we?
Step 1: Surf to Dynamic Drive's Lightbox image viewer page.
Step 2: Download the file lightbox.zip
Step 3: Extract the contents of the lightbox.zip to your hard drive. You will see the folder named "lightbox" and its contents below:

Figure 1. Contents of lightbox.zip

• lightbox.js - the main script.
• lightbox.css - basic style and tricky PNG support.
• overlay.png - 80% opacity, black tile used to create shadow.
• loading.gif - mock status bar used in examples above.
• close.gif - 'X' graphic placed in top-right corner.
