Highslide JS is an open source JavaScript software, offering a Web 2.0 approach to popup windows. It streamlines the use of thumbnail images and HTML popups on web pages. The library offers these features and advantages:

* No plugins like Flash or Java required.
* Popup blockers are no problem. The content expands within the active browser window.
* Single click. After opening the image or HTML popup, the user can scroll further down or leave the page without closing it.
* Compatibility and safe fallback. If the user has disabled JavaScript or the JavaScript fails in any way, the browser redirects directly to the image itself or to a fallback HTML page. This fallback is able to cope with most exceptions and incompatibilities.
