What is JSviewer?

JSviewer is a robust, highly configurable, dynamic HTML image viewer written in JavaScript. You can create a slide show with JSviewer in a matter of minutes. JSviewer was designed to be easy to use for both web masters and end users, yet have very powerful features. JSviewer supports keyboard controls for controlling slide shows.

How to Upgrade

Upgrading JSviewer is easy. Simply replace your old jsviewer.js with a new one available here. If you customized JSviewer using cookies, you may need to reconfigure them for JSviewer 1.3. Cookies were redesigned in JSviewer 1.2 to take up less memory in the browsers cookie cache. Review the configuration page for details.
