feh is a tiny image viewer for X11 that is primarily configured via the command line. It is very versatile and I primarily use it for setting the desktop background
Set the background for the desktop environment. If the
~/.fehbg file doesn't exist, setup the bitmap wallpaper isntead. Add this snippet to the xinit user-level scripts.
if [ -f "$HOME/.fehbg" ]; then $HOME/.fehbg else . $HOME/org/config/lib/shell/xrdb_colors xsetroot -bitmap ~/org/config/lib/bitmaps/tile.xbm -fg $XCOLOR0 -bg $XBACKGROUND fi
