How does Facebook Sharer select Images?
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.

I've got some image on our site where I included the Open Graph tag og:image.
For example the main company logo has such a tag as it should always be selectable and then there are some article pages or news and the lead image of those pages also has also the og:image tag.
When I test it using the sharer button on our page or browserbar-button (or any other way) the share dialog does only show me the image of the article page and not the company logo for selection.
You can test it here:

Funny thing is, that if I use the Facebook Debugger Tool the images (2 images) are all there:
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.up-great.ch%2Funsere-firma%2Fwegbeschreibung
Why is there a difference between the debug tool and the share dialog? (Btw, I know that I don't use og:url tag but I once added it to the page and there was no difference even after resetting the Cache with the FB debugger).
FB sharer bug oder am I doing something wrong?
One year later still no answer.
I just tried the same and it doesn't work neither in your nor in my testcase: http://mattweb.de/open-graph-multiple-images/
To me it seems Facebook changed this to one image only, but it's not documented anywhere.
I remember once it worked (even without Open Graph tags) but couldn't tell when that was. Now I know that it must have been more than a year. So thanks for your question.
Regards,
Matt
The ShareThis Facebook button will only pull the logo as an image to choose from a page. I am not sure why this is the case since I have other images on pages that I am trying to share from. Can someone help me out with this. I am not really familiar with the ShareThis API. Thanks for any help or feedback.
I tried using the Facebook URL Debugger: https://developers.facebook.com/tools/debug. When doing so, Facebook found all the images on the page, but ShareThis doesn't seem to do the same. That is why I am guessing it is a ShareThis related issue.
The client wants the person posting the page/blog post to be able to select the image from the images on the page. This is normally the case with the ShareThis API, but does not seem to do so. Otherwise I would have just used the open graph option.

1-30-14: I tried specifying an image with open graph meta on a page. The image was larger than 200 x 200, but it still did not work.
This appears to be happening on every page of the site.
Note: I did not build this site. It was built in Adobe Muse by someone else.
This is not a real answer, but I have to use the space here, to get you all the details of what I found out.
On the debugger it says https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.atranquilnook.com%2F :
Provided og:image is not big enough. Please use an image that's at least 200x200 px. Image 'http://www.atranquilnook.com/images/header-home03.png' will be used instead.
Since there is the image with the couple, which is bigger than 200px x 200px, I do not know if this is the answer, but you could try by uploading some bigger image.
Although the whole warning is deceptive, since a line above it states, that there is no og:image.
Looks like you are relying on Facebook being smart enough to find "better" image on your site. What you should do instead is adding a meta tag in the head section of your page.
<meta property="og:image" content="http://www.yoursite.com/img/some-image.jpg"/>
This will tell Facebook exactly what you want to rest of the world to see.
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
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

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.
