I've successfully added a Share button to my website using the following code:
https://developers.facebook.com/docs/plugins/share-button
It produces a popup with a link to the og:url along with the title of the linked page and a picture from it, which I can then post, and it shows up on my Facebook.
I am having 3 issues with this:
I've update the og:url and data-href after page load, using jquery, but the new values get ignored when I Share.
the og:title, og:description, and og:image don't appear to be used at all.
Sometimes I'd like to Share some custom text (and images if possible) without any url.
I'm aware that Facebook provide other tools/APIs that provide more versatility but it seems that would mean my site would have to go through a review process, and I'd have to code for security. This is not an option and I want to stick to the popup method.
Hope someone can help. Many thanks.
If the tags do not change when posting, refresh (and test) the tags in the debugger: https://developers.facebook.com/tools/debug/sharing/
Dynamically created Open Graph tags (with JavaScript) will be ignored, the tags have to be in the original page source.

I have inserted the OG meta tags in my pages and also have provided a simple link to help users share the contents on the Facebook using the
https://www.facebook.com/sharer/sharer.php?u=[the-urlencoded-link-to-my-page]
link. But I have two problems:
When attempting to share the content for the first time, the
Facebook sharer page only displays a preview box which only contains
the name of the site, and makes me use the Facebook's Object
Debugger to
fetch the meta tags. How can I automate this process?
And secondly, while the Object Debugger report says that it has
found the og:url, og:type, og:title, og:locale,
og:image:width, og:image:height, og:image and the
og:description raw tags on the page, but the image doesn't get
displayed in neither the preview box of the page nor on the shared
status. What I have missed? What's wrong?
To make things clear, sharing on google+ works perfectly (the image gets displayed, the title and the descriptions are in place.)
Thanks in advance :)
The original method for sharing links with a custom image, text and link appears to have been stripped from Facebook. I for one would love to see them bring this back.
Here is my situtation. I have a Facebook tab that loads a page that is hosted under my hosteddomains.com. I setup a Facebook app to work with my Facebook tab. When I try to use the new "Share Dialog" if the link I want to share is not the same as the app domains then i get an error and I can't share the link. Am I doing something wrong or is this what they intended to do?
IF that's what they intended to do then there is no way that this will replace what sharer.php could do. I could be on any site and share any link with an image to Facebook and have it posted to my wall.
The question is if i am on facebook tab and i want to share a link (I want a dialog box with a custom photo, title, link, and summary) and allow my users to post this custom message to there Facebook status.
Maybe i am confused about how to accomplish this, but so far i am not having much luck.
I miss the good ole days when i could just construct a URL and that would give me the ability to share what i want to share. Twitter and Pinterest have these methods.
Here are some code examples of things that I've tried that did not work:
Option #1:
The url in this option goes to page that I created on hosteddomains.com that has the Open Graph Meta Tags in it. My idea was to share these pages from my server that will direct them back to my Facebook tab. The result I was getting from this method was seeing the title of the tab from my FB page and description. The reason turned out to be that if i set the og:url to my Facebook tab page, that's the page that would get scraped. That's not what i was expecting from this method. I thought it would take the meta tags from the page i shared and the url with it. Not take all of the info from url and ignore the meta tags.
<a href="https://www.facebook.com/sharer/sharer.php?u=[URL]"
target="_parent">SHARE ON FB</a></p>
Option #2:
Tried using Facebook Share Dialog. I had an interesting time with this one. I setup a new Facebook app. I tried the Facebook tab as the URL and also my custom url to the page that has custom open graph meta tags. The facebook app has two App Domains - hosteddomain.com and websiteA.com. I also created a Page Tab section. The page tab section loads the HTML page that was loaded in the tab we made for our facebook page. Issue with this method is I don't get a custom open graph options set from my php page. I'm picking up information from the facebook tab again. At least now the dialog box shows the name of the new app. I am limited in what i can share using this method. The url i share has to belong to the App Domains. In order to have multiple app domains, I had to make that Page Tab section and then add the second url to the App Domains field, otherwise i got a warning.
<a href="https://www.facebook.com/dialog/share?app_id=[appID]&display=popup&href=[url]
&redirect_uri=[url]&ref=s" target="_blank">SHARE THIS</a>
Option #3
The last thing I tried was the fb-share-button using the Javascript SDK. I get the same result as option #1. I don't think there is much difference between these two. Option 3 here is a bit easier to deal with and cleaner code. In this example, the url is to my custom page on hosteddomains.com that has my custom open graph meta tags. That doesnt seem to matter though. It still pulls the info from the og:url meta tag. I tried removing the og:url meta tag. I get the same result. Is it the Page Tab info interfering?
<div class="fb-share-button" data-href="[url]"></div>
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.

Matt
I have a Facebook Like/Share button on a webpage. When you click the Share button, a window pops up allowing you to share a message about the site. There's a photo in the popup as well, which is derived from the webpage the button is on.
The problem is, that webpage shows a composite photo, an image on top of another image, and instead of showing the whole composite, the popup shows one piece of it.
Is there a way to use a different image entirely on the Facebook popup window, some specific image that's not present on the webpage? I had thought the og:image meta tag would do the trick, but it doesn't seem to work.
Thanks.

Got it. My problem is that the info I need from the Facebook Developer pages is either incomplete or not presented in a way I can understand. So for the benefit of others in my boat:
It's not enough to add the Like/Share button javascript code and div tag (where you want the button to appear). You also need to add a group of meta tags in the <head> section of your html page. (Note that in the Facebook Developers "Like Tag" page, the phrase "meta tag" does not appear.) The meta tag format is this: <meta property="og:type" content="website">
There is apparently a lag between your adding these meta tags and Facebook finding them. Some have said this is because of the way Facebook caches its content. In any case, you can bypass this lag by using the Facebook Debugger https://developers.facebook.com/tools/debug/ You enter the URL of the page with the buttons, and it tells you what's missing from your code--and at the same time it now recognizes any new additions, like new meta tags.
It turned out I needed meta tags for og:url, og:title, og:image, og:site_name, og:type, and og:description. I also discovered that the og:image tag needs an absolute url.
I found out about a lot of this not from Facebook but from here: http://davidwalsh.name/facebook-meta-tags
The Debugger is now telling me I still need fb:admins and fb:app_id tags. To get those I apparently have to create a Facebook App, which I'd rather not do. I hope it's not necessary.
Now that I've added these meta tags and run my page through the Debugger, I'm now getting the image I want showing in the Share window.
I use the meta tags in the exact way the instructions say. So when I click on the like button, I indeed have the correct information on my facebook page.
Yet, when I slightly change the meta tags' code (for example if I put another image or if I change the description) the changes do not take effect on the facebook like button, which continues to show the previous information.
This is very disturbing, because by mistake I put same link in the meta property="og:url" for two different pages, so when someone likes one of them, the other ones like button is also "pushed". And although I've corrected the code, the problem with the like button, as I said before, remains.
You should be able to edit your Open Graph tags at any time. The only exception is title is fixed after 50 likes and type after 10k
http://developers.facebook.com/docs/opengraph/#edit
Facebook has to scrape your pages to see the changes to the Open Graph tags. You can force this by using the debugger/linter.
