Thanks for the clarification.
Here's what happened. I put the Atahualpa suggested codes in the Layout Container, and the Header Image as well as the RSS/Comments icons shot completely out of frame. So I ended up deleting the Logo codes, and now my Header Banner is perfectly in place, occupying the entire header section.
I actually don't mind just having one image in the Header because my site name is pretty much part of the logo. Right now, it looks fine and it works for me without the two separate areas (Logo/Banner). But I hope there is no harm in deleting the Logo codes.
As for the RSS/Comments icons, for some reason, when I deleted the logo codes, the RSS icons disappeared also. But again, it actually works for me that the RSS icons are not on the Pages Menu Bar. I prefer to put the RSS & Twitter icons on a widget below.
i don't know why the RSS icons disappeared. As far as I know, the RSS codes are still there. I didn't delete them. But, if there's no harm in ignoring the disappearance, I'm fine with the way things look now.
