Joshua, I just went into your Texas gallery to look at the photo you're concerned about. It looks fine to me. Nothing like what that link above is showing. I also scrolled through Edward's images and clicked on "The Big Lick." It has more white space around it than your photo in question. But it looks fine as well. It's nicely centered and doesn't look strange at all.
So I'm wondering if it has something to do with your computer. It's all very strange indeed. I'm using Chrome as well. Maybe your Chrome has to be updated.
