This is a sincere question. I would really like to know the answer to this one.
I posted a link to one of my hubs on the WTH FB page.
The FB page selected a picture other than what I wanted. And it displayed the summary, which reminded me I needed to change that.
So, to make a long story short, I did the following,
Edited the hub, doing...
Clicking "do not display" on the photo capsule I didn't want showing.
Making the image I did want to show full width and at the top.
Fixed the summary text.
Also, coincidently changed the hub title.
Deleted the browser cache.
Signed out of hubpages.
Went back to the WTH FB page. Once again submitted the URL.
I kid you not, the following happened...
The same picture as before came up. Even though not displayed at all in hub. Even though no longer in browser cache. Even though I was signed out of HP. In other words, how and where did FB get that picture from and why?
The old summary also showed up, even though theoretically it should have been nowhere to be found.
And to really complicate the issue, the new title change did indeed show up.
So, we got new title, old picture, old summary.
Anyone who can explain this will be responsible for me learning something new today and will be highly appreciated.
The Facebook servers most likely cached the photo and description from the link you submitted.
I believe they cache based on the URL so you should be able to change the URL and force the servers to refresh the cache.
You could try using a link shortening service like bit.ly to do the trick.
If you look at the stats of that particular hub under "Hub Metrics" you'll find the short URL at the botom of that window.
I do not use FB but they were probably sharing the first one that you posted on there.
To be honest, Facebook does have these glitches where weird things happen. Sometimes it even stops companies from posting to their own pages!
I wouldn't worry too much. The idea is to get across the message and make sure that the pics in the hub are relevant, otherwise they will be irrelevant no matter where you put them
FYI, this has happened with me a lot when I post my hubs on my fb fanpage. I never know which image they will post. Not sure why, though. Sometimes it's the image I want which is at the top and sometimes it's an obscure one at the bottom. I deleted some of the posts of hubs that have been edited.

Sometimes I change pictures and titles to my blogs to make them more appealing when I share them on social media, but I've noticed that sometimes the picture and title remains as the original when I do this sharing for...

I don't spend a lot of time on facebook. I wake up, I make breakfast, I check my emails, read the news, and if I have time left - I'll glance at my facebook page and see if I have any messages. But why do you feel I...

I've noticed something kinda weird, after I write something, I put it on Facebook, because I've worked hard on it, and letting everyone I know that I have written a new hub. Do they or even even disliked it or leave...

So I'm replying to a comment on my hub and upon scrolling through the hub (I always check for errors or how I can improve), I see the related hubs section. There are five hubs there including one of mine. What...

Ok, I asked about this before, but couldn't figure out where I'd seen it and nobody could tell me what it was due to my cluelessness, but here it is again on a hub I just published:So, where does that come from? Is that...

From your experience which platform is better of the two, as far as promotion of your work is concerned? Some of my friends tell me that google+ is likely to do better due to its G connection. What do you say?
