You need a photo paper that is designed for black paper (which has a white background). It would then need to be contour-cut to the photo, otherwise you will simply be ironing a white rectangle with a photo on it to the shirt. You could print black on the whole thing and trim the edges if your printer leaves white margins. If your ink is not as black as the shirt, however, it will be glaringly obvious.
However, for what you are displaying there, you would almost definitely need it to be screen printed onto the shirt. Also, there are no black shirt transfers that get as good reviews as the JPSS for white shirts does. They tend to be heavier, feeling like a sticker glued to the shirt.
