Vista - RE: EventTriggers not compiling..

Well, unfortunately for you, the "Source" in "SourceUpdated" isn't what you
probably think it is. This is an event to determine whether a databound value
(one-way or two-way) has changed since the binding was first established.
It's not Source, as in Image.Source.
You could get the trigger in question to resolve with
"Binding.SourceUpdated", but you'd be triggering off something that would
never happen, because you don't have any bindings going.
You might want to try triggering off Loaded or Unloaded instead. With
Loaded, you'll have to fight the fact that the first time the image is loaded
with its initial value, the event is raised also, so maybe Unloaded is a
better bet? I'm not exactly sure out of context how your opacity fade is
supposed to match with user action.
