How can you come up with a parallax PICTURE (not the background)?

Question

css

The client wants it to move up and down as it scrolls. But this is a regular picture with a dude, not a background.
I tried to ask more specifically, but I didn’t understand, and then I’m already afraid to seem stupid.
It seems to me that only the background is allowed for the text to roll on it, but the chela needs it. on this picture parallax, so that the dude was up and down What to think?
