kindleleader on "Twenty Ten - Header Replaced by Photo in Post"

Using the Twenty Ten Theme -

When you click through to a specific post away from the home page, the header changes to whatever the photo is on the post. I don't want it to do this. How do I make it stop. Also, can't edit CSS, so I haven't changed anything with the coding of the theme- unless this is typical, then I guess I'll need to- and I would still need help! Thanks!
