Query NSImageView's current image?

I am able to set my image view’s image using the following:

theImageView's setImage_(theImage)

How can I programmatically determine which image is currently set within an image view? For example, if the image is a green_dot or yellow_dot etc? Any help would be appreciated. Thanks. --Andrew

Get the namme with something like:

theImageView's image()'s |name|()
