Feral Heart

Hi! I'm pretty new to FH, and I want to take screenshots of my characters (so I can draw them myself haha). I know one way to take a screenshot is pressing the "Print Screen" key on your keyboard. I have done this for all of my characters, but I cannot find the screenshots anywhere in my files. I have Googled where to find them, but none of what I've found helps me all that much. What do I have to do? Any help on the matter is greatly appreciated!
