ahoviewer is a GTK image viewer, manga reader, and booru browser. It brings local image viewing and online booru browsing together in a single desktop application.
The program can open individual images as well as archives and supported video formats. Its manga mode is designed for sequential reading, while the booru browser provides a separate workflow for searching, viewing, and saving online material.
Navigation is strongly keyboard-oriented, but the interface also exposes thumbnails, scrollbars, a status bar, and other viewing controls when required.
This is free and open source software.
