here is what you do if you have paint:
scan or convert pix into jpeg format.
you might have to reduce the size.
copy to word
use the drawing tools in word, arrows, lines etc... all of it.
save it when done.
copy again
open in paint
save it again
it will show all in your picture file as a tgif format.
save it as jpeg again, crop it and save it....
easy, once you done it
good luck
