League of Legends (LoL) Question: how take screen shots in game?

Ye just ctrl + V it into a paint file.

There's no sound, unfortunately. The computer will automatically copy it to your clipboard, even if you feel like nothing happens. To find the (single) shot taken, open up Paint or something and press Ctrl + V or Right Click -> Paste.

You can only screenshot one picture at a time. Any additional screenshots you take will override your previous one.

Also! Make sure your LoL client is set on "windowed" on the in-game settings. Otherwise, if it's on "full screen", it'll just be completely black.

i already tried this but it seems not to work. is theres some kind of sound or anything to know if the capture was successful? also, where can i find the shots taken from the game? thanks for your help.
