iPad Air - deleted photo appears over and over again and copies itself The picture I've  received via Viber deleted already 40 times appears over and over again in camera roll and photo stream !

How do i delete?
i solve this problem :

1 open viber and find who send you this photo
2 delete the photo from the chat or the all conversation ( slide left + delete)
3 delete all copy of this photo in the gallery and from the deleted folder
