| Qdig - A Quick Digital Image Gallery
|
| Qdig is an easy-to-use script that dynamically creates an image
| gallery or set of galleries from image files stored on a web server's
| filesystem.  Qdig supports subdirectory navigation for organized
| presentation of any size image collection.  Qdig also supports image
| captions, and can generate thumbnail images and smaller resampled
| versions of large images such as digital camera photos.  Qdig is
| simple to install, just drop it in a directory with images and/or
| subdirectories that contain images.  Converting (resampling) images
| requires either Image Magick or PHP's GD extensions and some quick-
| and-simple additional setup.  There are dozens of configurable options
| for customizing your galleries.  The script runs stand-alone, or a
| gallery may be included within another page.  Enjoy!
