How to Install PhotoQT Image Viewer on Ubuntu 20.04 | 22.04 LTS

In this article, we will show you how to install PhotoQt on Ubuntu systems.

PhotoQt is a simple yet powerful and good looking image viewer, based on Qt/QML, published as open-source, and completely free.

It is an image viewer that relies on an interesting operating concept inspired by smartphones. While the motif is displayed full-screen, all edges except the right one serve as a trigger (when touched with the mouse pointer) for a control implemented in other programs via menus and toolbars. For example, the left edge is used to display the metadata , while the lower edge shows a bar with a preview of neighboring images. This leaves plenty of space for the actual image. On the other hand, if you prefer keyboard control, you can use various pre-configured key shortcuts that can be reassigned if necessary.
