[FIX] product: image changes not sticking everywhere

Fixes #20046

Simply reverting e5ef1c59172b7b8ebb1912e015fd41003ffc275d looks to
work *but* since I didn't note the repro case for the issue and don't
remember what it was it may re-introduce previous breakage. Instead,
ensure all "sizes" for the image are reset if any of the sizes is
present *and* Falsy by adding a final case to the conditional.

If any of the image fields is present and non-falsy one of the
previous branches will be taken, so we can just check that any of the
image fields is present at all (this implies it's falsy).
