Fix GIMP plugin path problem in python script (1 Viewer)

I have downloaded the batch_restore.py from
http://www.lionhouse.plus.com/photosoftware/gimp_plugins/

I'm using Windows XP SP3 With GIMP 2.6

I don't know any python, but I understand that this script uses
invalid path for windows "/home/gjd/restore"

I tried to change it to c:\res\ but it just does not work as it
expects directores to be separated like on linux by using "/"

On windows we use "\"

Could you help me to fix this script? I need to fix a few hundred
my family slides

Thanks
