Thank you everyone for the help! It was awesome!
But I think I know how to help you people like me; I changed my password and then couldn't remember it so I went on iTunes and pressed restore, and backed it up, right? But then it didn't work so then I finally realized that you have to press restore, and NOT BACKUP because then it just restores your iPod to the same password. But before you do this you have to import your photos so you don't lose them; how you do this is when you first plug in your iPod it will say import photos, or open file, so you press import photos its pretty straight forward from there.
Hopes this helps!
