I’m not even going to think about what people are doing on Snapchat that they need to save pictures sent to them without the sender knowing, but a new app has made this much easier. Snapchat, a service which allows users to send photos visible for a maximum of 10 seconds before deleting them forever, notifies the sender if the recipient takes a screenshot of a picture.
