Lightbox JS V2 is a simple, unobtrusive script used to overlay images on the current page. It\'s a snap to setup and works on all modern browsers. The module comes with a Lightbox2 Lite option which does not use the Scriptaculous/Prototype libraries; it is therefore less likely to conflict with anything else.

If your -// installation of Drupal exists in the root of your domain, i.e., -// www.yourinstallation.com then you shouldn\'t have any problems. The issue -// only occurs when Drupal is installed in a subdirectory, i.e., -// www.yourinstallation.com/subdirectory.

var fileLoadingImage =
-// "/modules/lightbox2/images/loading.gif";
var
-// fileBottomNavCloseImage =
-// "/modules/lightbox2/images/closelabel.gif";
var
-// fileBottomNavZoomImage = "/modules/lightbox2/images/expand.gif";
-// //Update to 2.02+

var fileLoadingImage =
-// "/subdirectory/modules/lightbox2/images/loading.gif";
var
-// fileBottomNavCloseImage =
-// "/subdirectory/modules/lightbox2/images/closelabel.gif";
var fileBottomNavZoomImage = "/subdirectory/modules/lightbox2/images/expand.gif"; //Update to 2.02+
There may be other methods that can be used to achieve this, but this should be the simplest for those with little or no programming experience. If you choose to use Lightbox2 Lite option, then you will need to edit the lightbox_lite.js file in a similar manner on lines 39 and 40.
