pekwm
Be sure to make your own file at $HOME/.pekwm/autostart if you use pekwm-session to auto-launch commands when you startup. I know pekwm has a start file for this, but my method launches it only at the start of your session, while the method pekwm uses starts everytime you restart/start pekwm. Use it well. You can find an example below:
dbus-session --exit-with-session --sh-syntax & feh --bg-scale "$HOME/.foo/bar" &
