Geeqie is a lightweight image viewer. It was forked from GQview. The development is focused on features for photo collection maintenance: raw format, EXIF/IPTC/XMP metadata, and integration with programs like UFraw, ImageMagick, Gimp, gPhoto, or ExifTool.

New features include extracting previews and thumbnails from many RAW formats (requires Exiv2 0.18), improved speed (especially on dual-core processors), improved connected scroll and zoom controls, and experimental features for image selection and metadata editing. Back up your images before using the metadata editor.
