body: An art instructor who charges for his courses is using one of my photographs in his class. All the students including himself have painted the photograph and he has posted his painting on his site. I did not give permission to any of these people to paint my photograph. This is my most popular photograph which I sell in many shops in the area (I live in Canada). Is my copyright infringed and what can I do to remedy it?
