If you can calculate the location of the centre of the circle, and you get hold of the mouse location in the image mouseOver, then you can calculate the mouse distance from the centre of the circle. If you know its radius, then you can work out if you're inside it. This technique wouldn't work for more complex shapes, but for a circle it would.
