Imageindex generates standards-compliant static HTML galleries of images (usually JPG photos, but can deal with images of just about any format). Some features:

* Only out-of-date thumbnail/medium images are generated * Captions come from comments embedded in images (never get lost!) * Output is customizable with CSS stylesheets * Can fetch EXIF header data from digicam photos * Can optionally recurse directory trees * Index, detail, slide, and frame views * Can use mplayer for dealing with video files.
