Description:

QVV is image viewer based on TrollTech's Qt Toolkit! QVV is small,
simple, handy.

QVV is only few hundred lines of source code and handles as much file
formats as Qt does -- JPEG (all sorts of jpegs that jpeglib supports),
PNG, GIF, XPM and more...

QVV allows you to browse directories with lynx-like interface, view
images browse next/prev image while showing image window or in the
directory list, multiple image windows and directory browsers can be
opened/closed with a single key, panning easy with arrow keys or mouse
and few other things as well.
