Hi guys, if anyone is bored and would have time to look through this, I would really appreciate it.

I got this code from a website and want to overwrite a free tumblr layout with it.

When I put it in the "Edit HTML" box, the header and the pictures show up but the background is white. I wanted to have a jpg picture as background. No matter what I change or what I link to, it always comes up as white.
Does anyone know what could cause it?

HERE is the link to the html code I am using but I added this to it
<meta name="image:Background" content=" BLABLA.jpg" />
<meta name="image:Header Logo" content="BLABLA.jpg" />
