Send a message to the person who requested a photo of the grave monument of Thomas Smith with the following comment:
I wish to add the photo to my family tree. The first name on the headstone, Thomas Smith, is my 3x great uncle. I thank you very much for all of the work that you do to make this information available free on the Internet. Living in Canada, I wouldn't be able to get this information myself and I truly appreciate the work that you have done to make it available to me.
