My condolences first and foremost. I agree with you and the others. Let her know what happened with your sister, and that you would like it to come down. Let her know you are fine she took the pictures for her own personal reasons, but that they do make people feel uncomfortable. I have some pictures of my mom who passed away this past March, but took them for myself, not for everyone to see...as I knew it would be difficult for some family members.
