Hi, I just recently made an account on blogger, and it doesn't seem very customizable. I chose the minimal template, so it doesn't have a lot of stuff on it because I wanted to customize it myself. What I want to know is, how can I add my own banner to the site header? I couldn't even find an option to upload any files.
Did you know you can host the Blogger blog on your own webhost? Blogger's help section tells you exactly how to do it. It is fairly easy. Now if you don't have your own hosting and want to still edit it on Blogger you have to go into their section where they allow you to modify the templates. You'll probably have to still have the image hosted some where and point to it in your HTML. Hope this helps!
You can customize your blog and can upload new template. You can add header image by uploading your header to flickr.com or to any site, then get the url property of that header. In the blogger temple > Edit HTML> then search the /* Blog Header css, #header {, edit the background:url.
