When I do my own transcriptions from an image file, the image can be used as a source for any person in the household. I put the relevant source data including page number. Households may be split between pages.
Familysearch makes it easier as the data is already sourced and is listed for each individual member of the household uniquely. Everyone in the household, however, is keyed to the head of the household: David Hughey in the household of Robert Hughey. Clicking on different family members, say Richard Hughey, would change the references point to Richard in the household of Robert Hughey.
