Header Image
The header image doesn't come with the template file. To have the header image in your blog, save this image into your computer. Then, upload the image into the Page Element titled Header in the Layout section. As per license requirement, give a link to the image provider as mentioned in the credit section above.
If you want to use your own image for the header, the image has to be 896 pixels wide (with any height) to fit the header nicely
