I posted a couple of my website's links on my facebook page,
however the image url (og:image) for each of these pages has changed,
so the link posts on my wall still try to show the image from the old url (which doesn't exist anymore).
How can I make facebook recrawl these links, so that the correct image is shown?
Thank you.
In theory, if you input your url in the debugger (https://developers.facebook.com/tools/debug) it will re-crawl your web. It actually shows you the current result of crawl but I had have to wait several days and even weeks to see the results in my wall.

When I share a page from my website, I have ANY thumbnail attached to my post on Facebook. But, if I preview my page with the Facebook debug tool, Facebook is showing me the thumbnail.
You can try it here developers.facebook.com/tools/debug/og/object/
In the input URL put this page: http://www.team-exodia.fr/forum/threads/ouverture-de-la-section-garrys-mod-darkrp.6641/.
Now you see the thumbnail if the page is shared.
But now if you share this you didn't see the image preview on Facebook.

This issue is all of my page on my forum. I don't understand.
Does anyone know what's happening here? Thanks.
It works fine for me, although you do not have any Open Graph tags on your website. You should ALWAYS include them, the debugger tells you about that too. Here´s a nice list of the needed ones: http://ogp.me/
Dont´t forget to refresh the URL(s) in the debugger after changing it, the Facebook cache can be tricky.
I use Facebook share button to share my article (Title, description and image) on Facebook using Open Graph Meta and other default Meta
And my articles are echoed in post.php page like (mywebsite.com/post.php?id=post_id) which contents differ through post_id.
Well, while sharing a post on fb, facing some problems.
1: fb share doesn't detect the image belonging to the article/current post that is shared. (Thought the image URL in my Open Graph Meta is correct) and after sharing it on Facebook the link doesn’t redirect to the exact URL (mywebsite.com/post.php?id=post_id).
2: the fb share button is in my post.php page which shares different posts but sharing is counted same for all posts.
The FB share button has got an attribute (data-href="url-to-share") which my one is (data-href="<?php echo'post.php?id=post_id';?>").
Anyone know what and where is wrong with my code/URL addressing?
If your meta tags shows correct data then must be fb issue. I faced similar problem before.
Try debug your url in the FB debugger( https://developers.facebook.com/tools/debug/og/object/ ). It helps.
Fb haven't grab your updated data because they have their own time/interval to grab new data from the website(if im not mistaken). Using the debugger u'll see how the share will look like and show missing details if any.
If you view the source code of an example page, and the Facebook debugger for that page, you will see that Facebook scrapes the correct image and displays it in the Facebook debugger. There are no weird redirects or filenames going on here, just a simple image set to og:image, but Facebook doesn't show it!
If you copy/paste the url directly on Facebook (for example, in a status update), the og:image shows up immediately.
However, when liking or commenting from the site, NO image shows up at all!
Any help would be appreciated.
Thank you.
//create an object
FBGraphObject object;
//open graph object will be posted to facebook
object.provisionedForPost = YES;
Putting your page into Facebook debugger produces this warning:
The image referenced by the url of og:image tag could not be downloaded.
It is also for some reason chopping the ends off the og tags in your page, deleting the 'IMG_0325.jpg' text. I can only imagine this is because it doesn't like the capitalisation!
Our site has been suffering owing to a recent change in FB's acceptance of urls for images which it will show in posts, I think we have a slightly different problem to yours but they seem to have become more restrictive about the url being a very vanilla image url.
When i post a video link on FB wall, the first time the thumbnail appears,
then i delete the link from the box, and write it again, this and now the thumping dissapers.
this is a link for example, the first time facebook will show it.

Regarding the conversation above, it's Facebook's mechanism. Can't help. Assuming you are the writer of the page, you have already put the correct OG tags to the page head, so nothing you can do.
My friend has created about 20 Facebook fan page for the website. www.AvailDiscounts.com
Now the issue is, when we click on the wall post to "share" with other friends, its taking to another page where it displays the meta tags and the title of the login page instead of displaying the exact post.
Please find the fan page of the website:

Please help
As far as i have checked this seems to be an issue with the RSS Graffiti application in Facebook.
You have two issues here:
1) Are you posting the correct link in RSS Graffiti?
It seems all of your fan page links redirect me to the Avail-Discounts-Chicago home page. It's either it is non-existent, deal closed or bad URL supplied.
2) RSS Graffiti posts differently than Share button
RSS Graffiti prepares your data, image link title and description before posting to the page stream. The default Facebook Share button does not. What it does is get the URL, scrape that URL with information, which can be defined through opengraph tags. Make sure your links / deals have their meta:og's.
Your question is a bit vague, and the passing of the auth information is kind of scary, but anyway, I'd make the href of the post something along the lines of this:
