phpAutoGallery is an auto-indexing image gallery that uses mod_rewrite to make the application fully transparent to the user. It has on-the-fly creation and caching of thumbnails, resized images (configurable sizes), and directory listing. It is easy to set up, fully customizable through the use of Smarty templates, and generates valid XHTML 1.0 Strict and CSS 2.0 code. It can overlay copyright/logo images on-the-fly and display information about images and directories.
