How to take a picture In-game.

I know this seems like a total noob question, but how do you take a picture in SRB2? I read a post on how to do it once, but I forgot, and couldn't find it using the search engine (I tried "take and picture").
I already checked the wiki page concerning console commands, but I didn't see it there either?
I also read all the rules, and I don't remember anything at all in the manual at srb2.org either. Could somebody please help me?

And again, I'm sorry for asking a noob question.

Open the console and type bind x screenshot. Close the console and press x (or whatever key you set it to) and thats it. The screenshot will be in whatever folder you have SRB2 in.

In the autoexec.

Thanks, so much! I really appreciate it. God bless and have a nice day!

P.S. If I type a different letter, other than x, will it take a picture when I press that button?

Yep.

Also note that on Edge's setup won't screen your heads up display. You can use that in conjunction with "chasecam 0" to take some really nice screens.

Thank you all so much, for answering my question and for not calling me out on obvious stupidity!
