For >= openSUSE Leap 16.0 it's a KDE6 port, prior versions KDE5 port

KuickShow is an image browser/viewer with a nice filebrowser to select images
to be shown, slideshow support and the ability to display the following image
formats: jpg, gif, tiff, png, bmp, psd, xpm, xbm, pbm and eim.

Images can be displayed either in their own window, as large as the image, or
fullscreen (which shrinks images too large to display). KuickShow also has a
slideshow mode.
The program was designed to be very simple in its use so that it can be used
by non-computer experts.
