You either rename them yourself or you don't get to upload anything at all. I'm not correcting your mistakes for you, otherwise you won't learn to do it yourself. What you just did right now was incorrect.
Yes and the answer is no. You're not having those images restored until you go back and fix their headings. Look up other galleries, and you'll see how there headings are written. So don't waste my time telling you the same thing over and over.
Furthermore this is a wiki and not a gallery site. Our top priority is information.
