How to take a screenshot on SnapChat?

My friends have been showing me screenshots from their iPhones/IPads/IPods of pictures sent to them on The app SnapChat. I tried it and it didn't work. It always ends up taking a picture of the snap box. Is there a trick or a special way to do it?

You can take it but you have to keep a finger on the picture at all times. So basically you have to use three fingers, but when you take a screenshot it tells the sender that a screenshot has been taken.

Nope doesn't work

I don't think it works with the iPhone 5

Can't do I with the 4 or iPod 4

You have to hold the picture then hold the lock screen for a second or two (no it doesnt lock your phone) then press the home button

What is the lock screen and home button
