Changing Header in Default Theme II

OK, I’m inching along to a solution on changing the Default, blue-blob header- But I’m not there yet.

So far I’ve added a new jpeg as a test header and named it kubricikheader.jpg in /wp-content/themes/default/images

You can see it at https://www.jerusalemrepublic.net and my latest post shows what it is.

It’s there but behind the blob. How do I get rid of that blob? I’ve also tried removing the funtions.php from /default and also eliminating all text in the php. It seems this function is used to recolor the header, so I figured that without it maybe I’d pass Go. But that wasn’t the case. When I moved it, or its text, I got the full size blob back in the original color.

Any thoughts on where to go from here?
