I think if one of the project members could set up a Cemetery Free Space page for you, that you then would find it reasonably easy to upload the photos to the Cemetery profile.
What, in particular, concerns you about copyright? You would retain the copyright of your photos if they are uploaded, but that should also be the same for Find-a-Grave.
I have to say, I had to contact Find-a-Grave about cemetery photos that had been posted there that had been uplifted from WikiTree (ones that I had taken) without my permission. However, I have also, in many cases, made my photos available on both sites. My expectation is to be contacted, whichever site is used, if people want to use them elsewhere.
