Over the past few weeks we have been finding that facebook posts (not shares from the in-page FB button) have been failing to show the images tagged with og:image on our site. Our home page http://www.greatbritishchefs.com is an example. This seems to be a change in behaviour at Facebook's end because pages which were working a few weeks ago now do not. Also where a page is working currently, running it through the FB debugger causes it to immediately fail. Removing the og:image tag does not work. The images seem to be the right size, and the debugger results are free of errors regarding the image.
Would be grateful for help from anyone who is also experiencing this.
OK I found the resolution to this. What appears to have happened is that Facebook has become much more demanding about what kind of image urls it will work with in posts. The images on our site are sourced through a handler which preprocesses the image, putting a watermark on, resizing etc. and therefore the url might look like:
http://www.greatbritishchefs.com/getmedia/0ecdeb1f-c194-42a9-b465-012004a6cd99/AYW001-Website-Edited-Featured-Bacon-Breadsticks-Closeup/?width=420&height=270&ext=.jpg
This will now not work. For some reason, the url has to be completely vanilla without any query strings and with a standard image extension. When I rewrite the url for og:image to follow those rules, the images reappear in posts.
Hope this helps someone

I've seen this is a common issue here on stack but it seems that the answer is always dependent on the specific scenario. I'm looking for a fellow coder to give me that "AHA" moment.
Problem: Ads posted to my website do not show the og:image content when shared to facebook until the ad is shared at least 4 times
I have thought about/ tried the following things
Checking the image size to make sure it's not large (128kb) is the norm. I compress all uploads.
Giving the ad some time to marinate before sharing (perhaps the fb crawler takes a while to cache the page)
I tried using the debug crawler tool on fb to see if I could reproduce the problem and I indeed could.
I tried sharing the ad to my own page regardless of the missing image to see if the image showed up on my wall. It did not.
The image will not show up on ANY shares until someone has clicked on the share icon on an ad at least 4 times. It seems to me like it might be some latency issue on facebook's part.
What could cause og:image to only show on subsequent share clicks?
Edit
Here's a test ad.
https://www.jdmxchange.com/Classifieds/Details/6ae72690-14d8-4bab-b039-3a2d79923794
Reading https://developers.facebook.com/docs/sharing/best-practices I found this, which might be just what you're looking for:
Use og:image:width and og:image:height Open Graph tags
Using these tags will specify the image to the crawler so that it can render it immediately without having to asynchronously.
This means, if you set the width and height of your og:image with tags, the image will show straight away.
UPDATE
Actually debugging your URL shows like this URL is redirecting to another page, and then another. Which makes me suspect the Facebook crawler is not able to access the actual OG meta tags you're using.
As a random test, I would add OG metatags to that last URL and see if Facebook uses them. But the actual solution would be to use URLs which are actually reachable to FB (no credentials necessary).
Upon sharing a link on Facebook with og:image and og:video tags it will, under the right conditions, consistently display the wrong thumbnail image. Our clients are having this problem but unfortunately I cannot consistently replicate the conditions under which this issue occurs.
Go to the QVC UK Facebook page and look for video shares (example post). You'll see that the thumbnail for the video is the QVC logo when it should be the image given in the og:image tag. When putting the link through Facebook's debug tool the correct image is displayed with no content warnings or errors. This only seems to be happening when the URL is shared for the first time as subsequent shares will display the correct image. The image is present on our CDN before the URL is shared on Facebook. When I did manage to luckily replicate this issue; running the debugger before sharing on Facebook did not seem to solve the problem.
Am I missing something obvious, is there something wrong with my meta tags or could this be a potential facebook bug?
I've seen that multiple people are recording the same sort of problem on Facebook however only this bug has been left open (as of June 21st). In a related bug report Facebook mention that their crawlers don't only look at the image in the og tag but also look for other relevant images within the page.
Is it possible that it is seeing the QVC logo used so many times on the page that it decides to randomly overwrite the one specified?
Thanks
-- UPDATE
This only seems to be a problem when sharing to Facebook pages as opposed to a user's timeline. Changing the image URL seems to have temporarily fixed the problem. This looks like a Facebook bug
I´m finishing my site in WP and everything seems ok but I can´t get the featured image from my posts to show when sharing the link in FB.
I tryed the debugger, it sees the image ok and returnes a 200 response code.
Debugger test result here
The image size is 300x227 so I understand there is no problem regarding size or proportion.
The Meta included about the image is http://www.momento-marketing.es/wp-content/uploads/2013/01/Blog-Analitica-300x227.jpg'/>
Does anyone has a clue about this? Thanks a lot.
I have experienced very wobbly Facebook behavior recently, ie the last few days. Putting page through the Facebook debugger (with og image correctly specified), it says that a particular image is less than 200 x 200 when it is considerably more than this.
Several pages that used to give thumbnails very happily no longer do. Yet one with a really big image (for the sake of Pinterest) with the image reduced in size on the page, is fine.
One thing that DOES upset Facebook - the image has to be hosted on precisely the same domain as the page. I found that when I used a shortened version of my domain name (which forwards to the full one), that prevented thumbnails appearing. Suspect that even a subdomain for one, and not the other, might upset things.
Same problem here...when you try to share it on your browser trough the mobile website, it shows the image.. Try to share a link and replace https://www.facebook.com/sharer/sharer.php?u= to https://m.facebook.com/sharer.php?u= and you see it works, so must be a problem in the desktop Facebook website
Wordpress has changed its requirements for showing images on facebook timeline or on a facebook page. Even I experimented a lot of things and finally found out a solution. Here is how to do it,
Download WPSSO plugin from wordpress.com
Install the plugin
Then navigate into the plugin settings and find the "Images" tab
Set "Open graph Dimensions" as 600 x 315
Now use images above the size of 600 x 315 in your posts
Cick save settings and now try debugging the post with your facebook debugger tool.
I am sure this will solve your problem. If problems persist do post them we will try to reslve it.

Despite the meta tags (the first one I never used before, but it came up in the addthis forums);
And the debug tool getting the data in a correct manner:
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.mondiales.nl%2F
The facebook sharer code does not use the image specified. No images show up at all, there is no thumbnail chooser.
Looking at the HTML of the facebook sharer page, the image is actually there! The thumbnail chooser has a display:none. And when posting the damn thing, no image shows up on the wall.
Stop using addthis and implement a like function using the just the Facebook API? But from what I read, Facebook does a request for the page to get it's data so the JS part should not be the issue, should it?
Did I overlook something?
There's a restriction on the width/height ratio of images shared, the ratio must be less than 3.0
Your image is too wide (211/66 = 3.19) - add some vertical whitespace and it'll share OK i think
For future reference this is mentioned on both the old Share Button docs and the Open Graph protocol docs (under 'og:image')
I've found that once I've posted something to my wall from the sharer or the app, if I try to repost it, it will remember the original image (or no image in your case).
It might be worth clearing the whole cache/cookies from your browser and see if that does the trick.
If not, you'll find that if you log in as another user of Facebook and they try to post it, it will pick up on the new image on their account and not yours.
I'm not exactly sure how Facebook caches the images.
I know this thread is old but this may help someone else with the same issue. FB caches shared urls along with the thumb images and descriptions. To update the cache, add a bogus parameter to your shared query string, like, "?v=1". This gets the latest og tags.

Ok guys.. I've researched this thoroughly- I'm at the end of my rope and my supervisor is getting pissed. Any help is appreciated.
facebook opengraph thumbnails do not work when I share pages from my site. I'm sure I have og:image implemented correctly. I have resized the JPG thumbnails to 130x110 pixels. I have even tried hiding another copy of the same thumbnails in the pages with display:none.
example page: http://www.classical917.org/houston_public_radio-arte_publico.php
from that page:
The Facebook debugger (formerly the Linter) picks up the URL of the image, but displays a blank box. When I click on the blank box, the image loads.
http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.classical917.org%2Fhouston_public_radio-arte_publico.php
When I post a page from my site into a Facebook 'What's on Your Mind?' box, Facebook gets the title and description from my og: tags, thinks for a while about the image, then loads with no image.
Is it because I'm trying to use the same logo image for every page on the site? Is that a no-no? Is there something wrong with my image (although I've tried several versions)? Am I being penalized for using the debugger too often? Does Facebook hate my site?
Thanks for any ideas or pointers on this. I'm desperate to fix it before I get called into my supervisor's office.. : P
Your site has 215 xhtml validation errors according to the w3c validator. Facebook may be having a hard time parsing your page with so many errors. It could also be a caching issue, although the linter tool should clean up the cache, and the linter tool is pulling in the image properly. It may also not like full path URL's. Try a relative path.
As a work-around, you could also try specifying an image the old way:
<link rel="image_src" href="/_images/logo-facebook-130x110-kuha.jpg" />
The rest of your questions are invalid (Facebook isn't penalizing you and they don't care if you are using the same image).
Try removing line break in the og:description meta.
