vend billedet

Jeg vil gerne høre hvordan jeg vender billederne i dette script
stop();

var total:Number;
var radiusX:Number = 175; // Dette kan ikke vende billedet
var radiusY:Number = 100; // Dette kan ikke vende billedet
var centerX:Number = 200; // Dette kan ikke vende billedet
var centerY:Number = 100; // Dette kan ikke vende billedet
var speed:Number = 0.010; // Dette kan ikke vende billedet
