Renee emailed me a solution and it has worked.
On the screen shot "site settings.png" you have the option checked "Show primary photos" only. That setting will give you exactly what you are seeing, only the primary photo for each person. As long as you actually uploaded all the media when creating the website, by not using that similar setting. they should appear if you uncheck that box.
If you have source media you are trying to show you will want to also uncheck the box in the settings to "Show Person and Family Photos Only". Otherwise the source media would not appear either.
