DESCRIPTION
gthumb is a feature-rich image viewer and browser designed for the GNOME desktop environment. It allows users to browse images and directories, view images in full screen or slideshow mode, and perform advanced operations like batch renaming, conversion, editing metadata (EXIF, IPTC, XMP), and creating web albums.
gthumb supports a wide range of image formats including JPEG, PNG, TIFF, RAW, and more. It integrates with external editors like GIMP, offers thumbnail generation, color profile management, and search capabilities based on tags or comments.
The application provides tools for importing from cameras or folders, printing, and extensions for additional functionality such as face detection or map views. Invoked from the command line, it launches a graphical interface for intuitive image management, making it ideal for users needing more than basic viewing.
CAVEATS
Requires graphical environment (X11/Wayland, GNOME libs). Not suitable for headless servers. Some features need extensions installed.
EXTENSIONS
Supports plugins for extra features like video support, RAW processing, or catalog management via Tools → Extensions.
KEYBINDINGS
Customizable shortcuts; e.g., Space for slideshow, F11 for fullscreen. See Edit → Preferences.
HISTORY
Originally developed by Paolo Bacchilega in 2000 as gThumb. Maintained by GNOME community since 2010s, with major rewrites for GTK3/4. Widely used for image management on Linux desktops.
