Frustration!

So I decided I wanted more control over my template and I decided to take the template from my original blog and use it here. The only problem is, it will not change the header image! As you can see, on my other blog I have a custom header I created and then uploaded by going into the page layout and editing the header, then telling it to use my image instead of the header text. I can do the EXACT same thing here and it will say it's saved the changes, but the header image doesn't show up on the blog! ARGH! Any ideas?
