See the problem statement (below)

Each image is a DU
Images can't meet the Guidelines on their own.

Hence, as written - the guidelines cannot be met by any site or page that
has an image on it.

I don't see how this would solve the problems. To be honest, I don't see a
difference.

A delivery unit (as it seems to be the understanding of the DI WG) is a
collection of resources with one "primary" resource and 0 or more
"additional" resources, that are fetched by a user agent after fetching the
primary resource without activation by the user (in XLink terms: 
xlink:actuate="onLoad").

Don't you define the "Web Unit" to be exactly this?
