Adding Lightbox to Omeka
Step One: Get the Lightbox Package
The first step is to get the latest LightBox 2 package from http://lokeshdhakar.com/projects/lightbox2, where you will find a quick explanation of how it works and how to get started.
Step Two: Modify and Upload the LightBox Package
Once you have the package, unzip it so you can upload the files into the correct places in your theme directory. We will need to upload the img folder, the lightbox-2.6.min.js file, and the lightbox.css file to the correct places in your theme's folder.
Upload the entire img folder to your theme's top directory. (Alternatively, you could upload the images to your theme's /images directory, and modify the lightbox.css stylesheet to look for them there.)
Upload the lightbox.css file to /yourtheme/css.
Step Three: Modify your items/show.php file
yourtheme/items/show.php file, add the following as the first line (before the line that begins
<?php echo head(
Look for the line that calls
item_image_gallery, and modify it so it looks like this:
<div class="element-text"><?php echo item_image_gallery(array('link'=>array('data-lightbox'=>'lightbox'))); ?></div>
In your theme's configuration, make sure that the Item File Gallery option is checked.
