This sounds more like an OGP problem relating to a social and/or SEO plugin (Yoast or All in One perhaps). Does Independent Publisher set meta tags with open graph protocol? I don't imagine it does.
If you view the source of the page (that does show the featured image in social media) you'll usually see something like the following in the header of the page:
<meta property="og:image" content="http://example.com/wp-content/uploads/photo_path.jpg">
This is the meta tag the social platform is likely pulling the image from.
It's possible that it's the case that the SEO/other plugin is automatically pulling the photo from the theme in one case but not the other. These plugins typically have settings to allow overriding the featured photo, using a default photo if one isn't specified, or not using one at all.
This sounds to me more like an issue with another plugin causing the problem and not the theme.

@johnjohnston Interesting that you saw my Huffduffer reply via micro.blog as I would have suspected you supported webmentions and would have seen it directly on your blog as a comment--though perhaps you did and, like me, you forgot the source once you'd gotten back to actually reply. Or from the looks of it you've finished some additional set up and have those pieces working now. From what I can see it looks like you got Brid.gy working properly!
Thanks for sharing some of your podcast recommendations. I saw your post on Castro and I'll have to take a look at it. I'd recently switched from DoubleTwist on Android to AntennaPod for it's ability to listen at faster speeds as well as the ability to jump forward/back in 30 second increments.
I'm sure I'll see you around both micro.blog, or more likely directly on your site. Cheers!
@swissmiss I haven't gone through it all personally, but some of the press from this conference is likely to be relevant: https:/

@swissmiss Delving into @adactio's suggestion a bit deeper, here's a whole list: http:/
@swissmiss This from @davewiner is in that genre: Anywhere but Medium http:/

I like the idea of the shared stories here. In some sense, it's part of the power of the indieweb wiki pages which conglomerate examples of how various people have implemented and documented pieces of how they've done things. on their websites. It's even better as a clearing house of these examples which are otherwise sometimes hard to find and come across.
