Is your Snapchat randomly taking screenshots, or saying it is taking Snapchat photos when it isn't? This happened to me too, and I contacted their support...
Turned out it was a glitch or bug in the app that they fixed in a later version. So my advice is go on the app store and download the latest version of Snapchat, this bug should be fixed once you do that.
Happy Snapping!!
By the way, if you're into apps like Snapchat, then I think you should check out the latest photo messaging app created by the team at Facebook.
It's called Slingshot, and it works a lot like Snapchat, except the photos don't disappear in 10 seconds AND you can only see someone's message by sending them a reply first!
Have a look:
