GetImage() takes a Hashtable of parameters, defined by the user, that describe how to render the ImageGenerator control, and returns an object of type GeneratedImage which wraps the image and is handled by its own handler. Note that in all other methods, we use type IDictionary as a parameter for flexibility, but GetImage() has to take an argument of type Hashtable since WebRemoting will not allow GetImage() to take a IDictionary as an argument since IDictionary is an abstract class.
