That sounds like a reasonable suggestion to me. Originally 'image'
only expected URLs, but now we allow it to point to an ImageObject
(which might also be a http://schema.org/Photograph) so I see no loss
of expressivity here. The 'photo' property is on thousands of sites
though (and 'image' on many many more). Perhaps it would be a start to
at least say that 'photo' is a subproperty of 'image', since anything
that's a 'photo' of something it's also an 'image' of it.
