Snapchat app: Does it really work?

Anthony Weiner found out the hard way how sending a picture can get you in big trouble. Weiner left congress in disgrace less than two years ago after he "sexted" naked pictures of himself to a woman.

But the free app, Snapchat, claims it can help keep your photos and videos private by setting them to disappear just seconds after the receiver opens them. It's become a popular way, especially among teenagers, to send inappropriate pictures - believing that after those few seconds - no one can ever see that picture again. But that's simply not true.

There are actually several ways someone can get their hands on your picture and post it for the world to see. First, the person you send it to can easily take a screen shot of the picture or take a picture of the photo before it disappears and keep it for as long as they want.

Information technology (IT) experts say there's yet another way to beat the Snapchat system.

"You use a special piece of software,” explained Tom Bridge, IT expert. “You can get that photo out of the memory of your phone without Snapchat ever knowing about it."

"There isn't much privacy on the internet at all,” said Nadine Beck, mother. “And we need to remember that."

Snapchat says it will send you a warning if someone does screen-grab your picture. But IT experts say there is even a way around that.

Bottom line: if you don't want others to see it, don't send it over the internet.
