Add photo for actress - IMDB has no photo for her.

How do I add a photo of an actress with multiple listings (Welcome to the Dollhouse, Living in Oblivion, etc). Her name was Rica Martins. IMDB has a biography but no photo of her. She passed away in 1999.

I have a nice backstage photo that I took of her when we were in an Off Broadway (NYC) play together. How do I add it to IMDB?
