How do I put a splash screen during shutdown?

Question

I'm able to put a splash screen on startup. As soon as powered on, a splash screen is shown till startx command is run.

I edited the script to put the same image (for now) while rebooting/halting. I want it to be shown from right after reboot command is given, to the time that PC is exactly powered off.

Right now, image is shown right after reboot command is given, displayed for a few seconds, then a tty is displayed, and the following is written on the screen:

map: vt01 => fb0 

raspbian ...
Raspberry login: map: vt01 => fb0 
Oops: Terminated

Here is the /etc/init.d/asplashscreen script:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          asplashscreen
# Required-Start:
# Required-Stop: $all
# Should-Start:
# Default-Start:     S
# Default-Stop: 0 6 
# Short-Description: Show custom splashscreen
# Description:       Show custom splashscreen
### END INIT INFO


do_start () {

    /usr/bin/fbi -T 1 -noverbose -a /etc/splash.png    
    exit 0
}

do_stop () {

    /usr/bin/fbi -T 1 -noverbose -a /etc/splash.png
    exit 0
}

case "$1" in
  start|"")
    do_start
    ;;
  restart|reload|force-reload)
    echo "Error: argument '$1' not supported" >&2
    exit 3
    ;;
  stop)
    do_stop 
    ;;
  status)
    exit 0
    ;;
  *)
    echo "Usage: asplashscreen [start|stop]" >&2
    exit 3
    ;;
esac

I installed this script via sudo insserv asplashscreen command.

How can I make this script run very first on reboot and stay till power off?
