I figured out WHO took those pictures of my grandfather and grandma's graves. They are both buried in Golden Gate National Cemetery in San Bruno, CA being my grandfather was a WWI veteran.
In any event, I checked the person out that did this and it is someone closely related to my first cousin, an old decrepit nosey, greedy woman that I have nothing to do with. She hated my father and my grandfather and when I told her my Dad had passed away she replied, "Oh good!". 
She also bilked me out of a load of money in 1975 as my grandma had left me enough money to go to college, money I never received. Said "cousin" lied like a dog and swore as a witness in writing that my grandma had left no will. I have this document I also have my grandma's will stating that she wanted what money she had to go to my brother and me to attend college!
Maybe I should POST that will on ancestry.com! 
Angers me something fierce ever since I found that will (after my mother died). I've been wanting to go after her for perjury as you can just bet that she got a cut out of that deal from my late uncle, the one that the lie began with. My grandmother was her aunt -- that is the connection.
As for the adoption, I got lucky on that one as most old records in Louisiana do not exist due to fires that have occurred over time, especially anything at all to do with an adoption, much less a mixed-race adoption (my mother was part Native American and was adopted by a member of the tribe that she too was affiliated with are my findings).
I found mother's first cousin and sent her a Christmas card and she called me on the phone and she knew that my mother was for real but was unaware of the fact that her aunt had borne a child out of wedlock in the 1920s so it was a slight shock. Said cousin has written an entire book about this family, a very old American family.
That was my mission and the yield is tremendous. I've traced mother back TEN generations and I too "qualify" to be a DAR should I care to do so but I do not; DAR = Daughters of the American Revolution which is a big deal to some women out there it seems.
Anyway, back to the pictures of the graves, at least I figured it out. I suspect the only reason those pictures were taken of the graves of my father's parents -- it is because my grandma was the aunt said old decrepit cousin and she has no pictures of her, that much I know (she wanted one and I hung-up on her).
