I use HeritageQuest (Ancestry), which is available on my home computer free thru the local library.
I enter a heading for each census: e.g. === 1850 census === in the profile.
First I copy their transcription of the census into the profile, including the citation, which I reformat somewhat.
Then I copy the Transcription URL:
Then I go to the image and copy the Image URL and add the image number, e.g. (17 of 93).
Then I add the date accessed.
Then using snipping tool I copy the census image and upload it into the relevant profile, I click on the line that says, "[click here to see the full-size original image]" and copy the resulting URL into the profile prefaced by these words '''''For a larger, clearer view of the census image below, click [https://www.wikitree.com/photo.php/b/bd/Prickett-122-1.pdf here].'''''
Then I go to the "inside text" of the image and copy that into the profile, add the size, e.g., {{Image|file=Prickett-122-10.jpg
|caption=1860 Census return for William B.F. Prickett
|size=575px}} .
I add an introductory paragraph with the high points of the census, e.g.
"=== 1860 census ===
: William appears in the 1860 census as a physician with $2500 in real and $200 In personal property living with his wife, Nancy, and four children (two sons, two daughters). Also in the household is a domestic named Mary Batten, 20 years old."
I add the census citation into the sources.
You can see what it looks like here:

I also link the census image to any other profile(s) in which I want it to appear, making such changes in the descriptive text as I deem appropriate.
