Changing the Default Home V9 Videos and Parallax background image

I’m attempting to change the hot air balloon image on the Home V9 Videos and Parallax background image. The image is currently the hot air balloons, which points back to (http://kriesi.at/themes/enfold/files/2012/04/2.jpg). I’ve added other images and videos to the page, however the hot air balloon image remains. Is it possible to remove this image, or am I better off recreating the page from scratch?
This page is not live so I cannot send you a link; however I can make remote support available if necessary.
