You're right.  The correct question was something more along the lines of
"How are we going to make it intuitive for people to be able to use the same
payload for multiple images?"

Are we going to always search for fallback/foo if we can't find normal/foo?
What about /foo?

I think it should be implemented once somewhere so that it's consistent.

Thanks,
