I'm not sure if the state this is in has Voyeurism laws but that is a good place to start. Then you have unlawful recording, various surveillance laws and lots of privacy law violations.
Of course if this woman has taken the images with a sexual intent (or used them with a sexual intent) then totally; throw the book at her :)
