ImageAlbum is an easy-to-use Web application for picture collections written in PHP (safe-mode savvy). It features user accounts with access privileges for entire collections or individual images, picture comments, automatic thumbnail generation, and a nice interface (which is completely template-based). Pictures can be uploaded using an upload form or via FTP (which is nice when you have a lot of images to upload). Images can be stored outside of the regular HTML directory used by the Web server to increase security.
