Qdig is an easy-to-use PHP script that presents a directory (or tree) of digital image files as an online gallery (or set of galleries). Qdig supports image captions and can generate thumbnail images and smaller versions of large images such as photos from your digital camera. You can configure many aspects of your Qdig gallery within the script. Qdig runs stand-alone or may be included within a larger page. A gallery management script provides easy browser-based gallery administration.
