I get where this would be incredibly traumatic for your daughter, but I don't see how sharing these photos with the world is helpful. It could even cause more embarasement for your daughter. I applaude you for being able to step up and get her help immediately. Hopefully her therapist has some ideas of what you can do to help her further.
Like Magdlyn said, there is nothing wrong with BDSM between consenting adults. If what happened broke boundries your wife and you had agreeded upon, then those issues should be addressed.
