Eye of GNOME
Eye of GNOME is the official image viewer for the GNOME desktop environment. Unlike some other image viewers, Image Viewer will only display images. It does, however, provide basic effects for improved viewing, such as zooming, full-screen, rotation, and transparent image background control.
Eye of GNOME will eventually be replaced by a combination of Sushi and GNOME Photos.

Image Viewer supports the following file formats:
ANI – Animation
