Hodge Podge glue can be purchased at Michael's or any craft supply place. Run your photos through the scanner and print out a copy to use. Trim and using a sponge brush coat back of photo and press onto chest. Then dip sponge brush into hodge podge and brush across the front of photo, going off the edges onto the chest. Keep going to you have all the photos in place. You can do this over days.
Let everything dry for 24 hours. Get yourself some clear valathane and another sponge brush and coat the entire chest according the the direction.
