I'm having this problem. I have reported it 3 times and have been told by separate help-chat-people to just wait. The photo I want removed is over a year old now. I respect that you may have got yourself in a design/development pickle, but you must understand the emotional response (unwanted) photos have, and the negative effect this has on the experience of a key feature of your software.
I deleted my Facebook account a long time ago, so I can't update it there, or re-sync accounts or anything.
