Screenshots

First of all... I love the game... apart from not being able to launch offline from my computer (Windows 8,1 - can't have DirectX 9).

The letter "C" allows me to take screenshots while in the game.

My problem: Where in the heck do I find them once I have taken them?

I am a complete technotard when it comes to computers so if you respond, do so in language that I might understand...kinda like you would should you try explaining this to say... a dog.
