WP Lightbox JS is a WordPress plugin that enable you to use Lightbox JS script to overlay images on the current page. This plugin also adds a “Lightbox JS†quicktag to the post window in the WordPress admin section.
What is Lightbox JS
Overview
Lightbox JS 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.
Benefits
Places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths.
Keeps users on the same page. Clicking to view an image and then having to click the back button to return to your site is bad for continuity (and no fun!).

After upgrading to the latest version of ImageManager I added WP Lightbox JS to provide a more user friendly way to look at the enlarged pictures. For an example look at Windows 2003 Terminal Services – What licenses do I need? Examples both with and without SBS 2003.
