Another transferring pictures to wood blog. good instructions here-update: works really good and a fun project! Just make sure you use a laser copy of the picture rather than ink jet (that does not work so well!).
I did this today! I used a photo printed on regular paper using my HP ink-jet printer at home, though. I didn't expect it to work, so I used an odd shaped piece of wood just to experiment with. I'm amazed. Don't know why all the tutorials say use only laser printed photos.
