    The two methods implemented in this class are part of the IKImageBrowserItem informal protocol:

    http://developer.apple.com/documentation/GraphicsImaging/Reference/IKImageBrowserItem_Protocol/IKImageBrowserItem_Reference.html    

    There are three required methods, but only two of them are implemented here. The third, 

        imageRepresentation, is provided by the Core Data binary attribute of the same name. 

        There's no reason the other methods in the protocol can't be implemented, but they are 

        not required for objects which will be displayed in the browser.
