Please be aware that if I take a volunteer photo for you, I consider it YOUR property to do with what you will including posting it to other websites.
Do I have one of your relative's graves listed? Ask me for a transfer. I would prefer that a family member maintain them rather than myself. The only transfer I would not do would be for close family members of my own.
