Just tried to view photos from the dolphin file manager. Default of Kubuntu Intrepid is to launch Gwenview 2.1.3 which is rather new to me.
It is a nice basic tool that still uses KDE3. This may explain why the Gwenview plugin did not detect the KDE Image Plugins Interface (KIPI) which is kipi-plugins version 0.1.5-1ubuntu2 at the moment. It still doesnt show the EXIF info of photos. Keyboard short cuts are still not completely incorporated for faster navigations.
The main configuration files are:
The slider bar at the bottom allows a neat quick a zoom feature.
Allows quick access to all photos. This includes basic editing features of rotation, mirror, flip, resize and crop.
