Thanks, that was it. I guess when I originally uploaded them, I overlooked setting each as Featured image.
For the benefit of other newbies:
1. Do NOT mess with functions.php. At least not in this situation. The advice I found online, saying to add a line of code starting with add_theme_support must have been about something else. That’s not even PHP code is it? Anyway, it broke the whole blog. Reverting to the original fixed that.
2. View the post. Click Edit. In the right-hand panel, click the Document tab. Click Featured Image in the list, then Set Featured Image, and either replace the current image, or choose it from your library. Remember to click UPDATE. There may be other formatting concerns, but that worked well enough for me. Probably self-explanatory from that point.
