I had a crack at it...

And I wish it was that simple.. But it's not

So sure I can create a state indicating the error.
But then how would I set my normal image if it's not an error?

I can't put my image type inside a state-type otherwise it's not a
direct children of my screen anymore, and I can't set it.

As you can't set a dependency on an image being displayed within a
statetype (I tried, that dependency never resolve), I would then have
to choose between the error being displayed, or the image I do want to
display. Or both at the same time...
