I have had a look at your method of downloading a census image from Ancestry and linking it to all the relevant family members which certainly is very easy. What I don't like is that the media now in each family members file has been given the same caption which includes the head of household name, not their own name. I assume that I can't change this under each family member without corrupting the stored image in main media collection - or am I wrong.
Also the media (census image) has been linked to four facts, birth, name, residence and sex which seems somewhat overkill. Am I being too pedantic.
