Eye of GNOME (eog) is the official image viewer for the GNOME desktop environment.
It provides a simple and user-friendly interface for viewing a wide variety of image formats, including common ones like JPEG, PNG, GIF, BMP, and TIFF, as well as many others. Beyond basic viewing, eog offers essential image manipulation capabilities such as rotating, flipping, resizing, and cropping. Users can also organize image collections, play slideshows, and set images as desktop wallpaper directly from the application. Its deep integration with the GNOME desktop ensures a seamless experience for quick image inspection and light editing tasks, making it a staple utility for GNOME users.

eog is designed as a basic image viewer and light editor. For advanced photo manipulation, a more powerful application like GIMP would be required.
While functional on other desktop environments, its optimal integration and experience are typically found within the GNOME desktop.

eog integrates deeply with the GNOME desktop, supporting features like drag-and-drop, context menu actions (e.g., 'Open With'), and automatic association with common image file types. It also allows setting images as desktop background directly from the application.

Historically, eog supported various plugins to extend its functionality, such as image effects or external editing integrations. While plugin support varies between versions, its core design emphasizes extensibility.

eog has been a core component of the GNOME desktop environment since its early days, designed to be the default image viewer. It has evolved alongside the GTK+ toolkit and the GNOME project, consistently focusing on providing a simple, fast, and integrated solution for image viewing and basic management. Its development tracks the general progress of the GNOME desktop, ensuring compatibility and leveraging new features of the environment.
