My website header was some how affected by a picture I updated here: http://nkdogwalking.com/about.html

I edited the picture, and then I realized it had affected the title in the header. Why did it do that, and what is the fix? The navigation tabs also shifted towards right. I just don't understand why something in the sidebar would affect the header. I did flip flop the paragraphs on the very same page with the same update... It could've been that, too. But I think it was the picture that did it.

Would greatly appreciate your help.
