This theme was originally developed to show off as many Zenphoto functions as possible and really to be used as a theme. It turned out to be an extremely simple theme that many people get excited about. There are two versions included, and one of them precaches the next image to make a great browsing experience.
This theme has been abandoned by the ZenphotoCMS team and we provide it for archival purposes on our "unsuppported-themes-official" GitHub repository "as is". We may sometimes roughly update it but cannot promise full compatibility with current ZenphotoCMS releases. Contributions are welcome.
