My Photo Gallery is a Web-based photo gallery that also supports non-image filetypes. It is easy to setup and even easier to maintain. Slick-looking image galleries and thumbnails are generated on the fly from any root directory that you specify. Albums can be created using the included Web-based adiminstration tool or by creating a directory and copying your pictures and files to that directory. A Web administration interface is available to help add descriptions, rename images, rotate images (losslessly), and more. It includes advanced features such as image logging, renaming, resizing, image rotation, smilies, and visitor comments. Unlimited filetypes may be recognized, and custom images for them can be displayed in your galleries, allowing you to archive MP3s, MPEGs, AVIs, etc.
