Ubuntu / Linux news and application reviews.

After more than a year since the previous release, a new PhotoQt version was released today - 1.1 -, which introduces some interesting changes such as per-session rotation/flipping, new Quick Settings widget, improved fake transparency and more. Also, with this release, PhotoQt switched to Qt5 and QMultimedia.


PhotoQt is a fast, stylish Qt image viewer for Linux and Windows, which uses GraphicsMagick under the hood, meaning that it supports 80+ file types. The application features basic image manipulation (flip, rotate, zoom) and file management (rename, delete, move, copy), customizable keyboard and mouse shortcuts, thumbnail cache, can display EXIF information, image slideshow and more.

PhotoQt looks somewhat similar to the "Lightbox" Javascript plugins available on many websites: it uses a semi-transparent background (this is configurable) with cached image thumbnails (by default, image thumbnails use autohide but you can make them permanently visible from the app settings) at the bottom of the screen which can be used to easily navigate through the images available in the current folder.

Changes in PhotoQt 1.1:
  • PhotoQt is now based on Qt5;
  • Phonon was replaced by QMultimedia;
  • Rotations/Flipping is now stored per session (nothing is saved permanently in any files);
  • Filter images in current directory by filename/extension;
  • Images ca now be scaled (permanent change);
  • Fade-in starts at the top of the screen;
  • New Quick Settings widget (fade-in widget on the right);
  • Fake Transparency (background) is now supported for any number of screens;
  • fix: restore from system tray preserves fullscreen;
  • fix: context menu converted to 'normal' shortcut;
  • fix: possible to select background image;
  • fix: saving settings no longer corrupts session wide list of known file formats.

By default, the PhotoQt Quick Settings, General functions and file info panes/widgets are displayed on mouse over and since this is a bit confusing, here's how to access them:
  • Quick Settings -> right edge of the app window
  • General functions -> top-right (top edge of the app window, near right)
  • File / Exif info -> left edge of the app window

Also, the application runs in full screen by default but you can set it to run in window mode from the Quick Settings (see above), by enabling "Window mode" and optionally, "Widow decorations".
