There is no such concept, "to call an event". Events are invoked, and this is very different from calling. Now, the thing is: in .NET, it is impossible to invoke any event from anywhere except the declaring type of the event instance. This is an important fool-proof feature of events, in contrast to "normal" delegate instances. If the type is not yours (say, you don't have source code but have to use some type from a library, presumably .NET FCL), and the type does not provide a method or a property which indirectly invokes that events, you cannot programmatically invoke it at all; you can only do it during runtime by operating a mouse or a keyboard.

But this is never needed. You can always write a method which you can call in two or more places: from some event handler and directly. You never really need to invoke an event, but you need to programmatically create the same effect as in case of event. In your case, it's even simpler: you just need to add a property used to change some image.
