How to change positioning of Full Width Header Images

Hey folks,
I've just started playing around with Upfront and Spirit theme and have replaced the sample image with a new 100% wide one as can be seen here: http://upfront.users41.interdns.co.uk/

My question is, can I change the position of the image, like top centre, centre centre etc without custom css and within the edit panel

Thanks in advance for any help
