Is this only when you're in Create-A-Sim at the start of a game? When you're using the Salon in game? A mirror or a dresser? When you say, 'when I come back it will be gone,' what precisely do you mean by 'come back'? Switching to a different color, then wanting to go back? Leaving Create-A-Sim and then re-entering to make a new sim? Exiting the game entirely, and coming back a day or so later? Then you can follow the instructions here to upload.
Screen shots would be to hit 'print screen' if you're on a PC (Mac method is escaping my memory at the moment).
