It turns out that you've probably been breaking the law ever since you downloaded Snapchat without even knowing it.
The government's culture minister, Ed Vaizey, has said that it is illegal to screenshot a Snapchat picture and pass it on without consent.
If the original sender was to report the person who shared the Snapchat, they could even face a prison sentence.
"Under UK copyright law, it would be unlawful for a Snapchat user to copy an image and make it available to the public without the consent of the image owner," the minister wrote on Parliament.uk.
"The image owner would be able to sue anyone who does this for copyright infringement.
"However, Snapchat advises users to avoid sending messages which they would not want to be saved or shared."
If your mate sends you a picture of his balls and you screenshot it to post it in group chat, you could face years behind bars.
"The disclosure of private sexual photographs or films without the consent of an individual who appears in them and with intent to cause that individual distress, is an offence under Section 33 of the Criminal Justice and Courts Act 2015," he warned.
"Those convicted could face a maximum sentence of two years in prison."
Might want to hand yourself in now.
