Great America season p? HELP.?

Okay so about a month ago I went to Great America and bought a season p and gave my info and took my picture. I have a season p card but it doesn't have my picture on it. Im going to go again next week and was wondering if you were supposed to have gotten another season p card with your pic on it through the mail? I was just wondering because I don't want to run into trouble and have to pay for ANOTHER one? And if you don't need one....how do they know its yours and such? Thanks for the help. Sorry for it being so long(:
