WhatsApp is rolling out an innovation that allows users to make photos or videos disappear after being viewed.
After the recipient opens the image for the first time, it deletes it, without saving it to a phone.
WhatsApp said the feature was meant to "give users even more control over their privacy".

However, child protection advocates have expressed concern that auto-disappear messages could help hide evidence of child sexual abuse.
The National Society for the Prevention of Cruelty to Children (NSPCC) is already at odds with WhatsApp's parent company Facebook over the use of encrypted messages.
Such encryption means that the police cannot see the messages "in transit" – only the sender and receiver can see them. But the automatic deletion of messages may mean that devices seized in police raids will no longer contain evidence.
