Snapchat dilemma. Kinda long

So my husband got a snapchat last night while we were watching a video on his phone and he asked me to check it for him, well when I opened it, it was from this girl we both went to high school and she was in the hospital with monitors all over her chest, but her entire chest was showing, nipple and all. They didn't have any previous other snap chats, but she told me while him and I first started dating she always wanted to be with him, but he was never interested in her. I kind of want to say something but I know she was doing this for attention and I don't really want to give that to her. On the other hand, I don't want her sending naked pictures of herself to my husband. Any thoughts on what I should do?
