I wanted a quick and easy way to show entire albums of pictures online. This solution allows you simply specify the path of a local directory of images, it finds the thumbnails and creates the pages for you

Picture Viewer 1 simply found existing thumbnails and generated a gallery based off that. Picture Viewer 2 automatically creates and caches thumbnails, for a much easier setup. It also has a nicer layout

Picture Viewer 3 retains the functionality of previous versions, but is a much easier setup. The root of every picture directory simply needs a one-line index.php file that includes the image_viewer script from a centralized location. Also added is slideshow functionality, and detailed picture information (exif). The layout of the pages is similar, but with a bit more polish.
