I'm using srandrd to recenter my wallpapers when I configure an external monitor (I always do it 
manually with either arandr or xrandr).

I just start srandrd like this:

srandrd -e -n ~/bin/srandrd-handler

~/bin/srandrd-handler is a shell script with an executable bit set and it contains only the following:

#! /bin/sh -
feh --no-fehbg --bg-center --image-bg 'black' "${HOME}/wallpaper.png"

Good luck!
