Lightbox 2 WordPress Plugin

WordPress plugin used to overlay images on the current page into neat Javascript-powered overlay popups.

16-12-2008 – Version 2 is out! Now from settings you can choose background-color, overlay opacity, resize speed and automatically add the lightbox effect to your post’s images.

This plugin includes the new Lightbox JS v2.0.4 javascript written by Lokesh Dhakar and and was then transformed into a WordPress Plugin by me. Use a title attribute if you want to show a caption. Click on the images below for an example.

  • De-activate the plugin.
  • Delete the old version `lightbox-2-wordpress-plugin` directory.


  • Unzip the `` file.
  • Upload lightbox-2-wordpress-plugin folder to the /wp-content/plugins/ directory.
  • Activate the plugin through the ‘Plugins’ menu in WordPress, go to Setting->Lightbox.
  • Add a rel=”lightbox” attribute to any link tag to activate the lightbox, or rel=”lightbox[roadtrip]” for an image set.
  • Optional: Use a title attribute if you want to show a caption.

Single example:
<a href=”img1.jpg” rel=”lightbox” title=”my caption”>thumbnail1</a>
Image set example:
<a href=”img1.jpg” rel=”lightbox[roadtrip]”>thumbnail1</a>
<a href=”img2.jpg” rel=”lightbox[roadtrip]”>thumbnail2</a>
<a href=”img3.jpg” rel=”lightbox[roadtrip]”>thumbnail3</a>
Tnx to my sister for the photos! Link me in your site!
