I wanted my elderly mother to have something special and recognizable on her door in assisted living. This does the trick! No instructions were included, so I first wiped that area of the door with some rubbing alcohol to clean off any residue. Then I thoroughly wet the area with water, putting a spare towel on the floor below to catch the runoff. I carefully peeled the picture from the backing and centered the picture on the door at what is eye-level for my Mom, who's in a wheelchair. Then I wet the surface of the picture itself and used a credit card to drag the surface, from the center to the outer edges, to get any air bubbles out. (Don't do it TOO hard or too much or you will scrape off the printed picture!)She has gotten SO many compliments on the picture, from residents, workers, and visitors! It's been one month, and the picture is still holding firm. It hasn't curled at the edges or anything like that. My Mom can instantly recognize her own door amongst the many that are on her hall, so it helps with that, too!
