Command line to capture screen

Recipe:
1 IrfanView
1 windows 2000 or above preferred

start i_view32.exe /silent /capture=0 /convert=.\image.jpg

/capture=0 whole screen

I would like to add this command before to my usual:

shutdown –f –s –t 0

 

 

i_view32.exe /silent /capture=0 /convert=.\image.jpg
shutdown –f –s –t 0

And even irfan_view could send an email before.
