Yes, it's a lame image. This is a test blog. Deal with it.
To make this work, look at Background Image for Blogger Template. Then:
- Search the template for the body CSS element
background:$bgcolor;
Add
background-image: url(path to your image); - Look for #header-wrapper, #main-wrapper, and #sidebar-wrapper
- Under each add:
background:$bgcolor;
This keeps the image from appearing under your text
- You might also want to add a section that says
#footer-wrapper { background:$bgcolor; }
I'm undecided about this as yet.
