Make an image rotate depending on menu hover mouse position : OK, so This may have parallel questions like [this one][1] but I still have not quite got what I am aiming at.

I want to make a png image of an arrow rotate to point to the tabs of the menu in a wordpress site - so if you hover over the menu link, the image points at it too, but when you mouse away, the image returns to normal orientation.

So, I don't want it to totally follow the mouse, just when the mouse is over a menu item.

Thanks.
