I got a question to ask. How do you take pictures of your classes in the loadout screen?
Press the Print Screen button on your keyboard (sometimes it's abbreviated) while in-game. After alt + tabbing or quitting, open an image editor (MS Paint) and paste the image into the document.
You can either do that or just take a screenshot in-game (F12 by default, I believe) and find the file on your computer. I think after you take a screenshot the dialog box gives you the option to see the location of the file or something like that.
