Photo move x y values?

Hi,

I would like to make the backround picture move slightly with X Y values on mouse over - simple sample here (please click “preview”) http://www.flashcomponents.net/component.cfm?nav=2&id=170
I have done the Moving an Object Using X and Y Values tut but do not really know how to change it to my needs.
Perhaps someone could help me out, please? I am sure a nice piece of code fits in here;)
