Although as artists who sometimes deal with nudity in an artistic way from time to time, we're very strict with our policies and careful with regards to nudity (full or partial) posted in the forum.
Most especially when it comes to one's personal photographs. It's next to impossible to ascertain ownership or identity of the person/s in the photos. And we wouldn't want search engines to latch on to the posted images in the forum which in turn may become a cause of embarrassment or litigation to photographer or subject.
But we would also want to help out people with your situation. You can't be blamed if you can't re-do the shot most especially if it were a candid, "one of those moments" photo opportunity.
