Mirage – lightweight GTK image viewer

Mirage is a lightweight image viewer designed to provide fast, straightforward image browsing through a traditional GTK interface. It is aimed at users who want more functionality than a bare image display window without the complexity of a full photo management application.

The program supports common image formats and includes thumbnail browsing, slideshows and basic image transformations. Users can navigate collections from the keyboard, inspect pictures at different magnifications and manage files directly from the viewer.

Mirage also supports custom actions, allowing external commands or applications to be launched against selected images. This makes it useful for people who want to combine a simple graphical viewer with existing image processing tools.

The maintained source available in Debian uses Python 3 and GTK3 through GObject introspection, rather than the original PyGTK implementation.

This is free and open source software.
