ZF TeamSpeak Photo-ID

I joined for about all of, eh, 15 minutes when I was banned for about a day for a lack of age verification.

Now, I did some research on the Teamspeak and I'm supposed to send something that confirms my age, picture wise but I have no idea what to send. It's probably really obvious and stupid, but like, if you want a picture of me with "I'm 18" in the corner of the photo I got MS paint. I do NOT have a license because I'm legally blind and can't drive so unless you want that badly wrote out "I'm 18" I'll need some instructions.

EDIT: I dug my ancient passport out, and I've sent it in. Should get some results within a day. Cheers to everyone who commented, sarcastic or not.
