Koko – image gallery for desktop and touch devices

Koko is an image gallery application developed by the KDE community. It provides a graphical interface for browsing, viewing and organising photographs, with a design intended to work on both traditional desktop computers and touchscreen devices.

The application is particularly suited to users who want to browse their photograph collections without the complexity of a full-featured photo management system. Its interface presents pictures as collections of thumbnails, allowing users to move between groups of images and examine individual photographs.

Koko forms part of KDE’s family of convergent applications, which are designed to adapt their interfaces to different screen sizes and input methods. This makes it suitable for Linux desktops as well as devices running Plasma Mobile.

This is free and open source software.
