Has anyone done this or know how? I will likely ask my housekeeper/ handyman to actually do it, but I want to know how it should be done to make sure he's not guessing either.

The tile wall is in the bathroom and it doesn't go up to the ceiling. The side I want to place the pic on is over the bath tub. The other side is the shower. The previous owners had a metal art piece that they used very tiny screws to place on the tile. The picture I have has four "teeth" and can be hung using screws or adding wire and a picture hook.

Thoughts? Tips? Definite how tos?
