My image path can't change please help

My default path to my files is www./wp-content/themes/atahualpa/images/header/
I've uploaded files to the images/header section of this theme and I have the most recent version..my header images will not show up no matter what. I go back to the theme options in wordpress to try and change it to http://www.e-styling.info/wp-content...images/header/
but am unable to modify that box..could that path be the problem or did I miss a step somehow..i've already removed the original images the template came with.
