It would have been easier to go w/o a separate object but I went this
way since 'image' is a separate node in the config and I would assume
its for a reason. One reason that comes to mind is that in future
there might be some other options being added here?

I didn't know of this cause one thing i didn't do was to read the
docs. :( I'll try and update.
