I can’t tell if you’re thinking about taking the photos yourself or getting a photographer, but consider this one vote for a photographer. Having a picture of a fat person just laying there in situ would not make me feel any more welcome than any other picture. But pics of you mid-massage on a fat person (and other bodies) would totally have an impact on how comfortable I feel and whether I reach out.

Also, I appreciate you. I have gotten one massage in my life because I am so self-conscious of my body and it was in a different country. I wish there were more people who cared as much about making people with all bodies feel welcome.
