Hello,
I want to set an own article picture for facebook, even when there's no featured media on the top of the page (for example with the standard article picture function, which is deactivated in Brightbox).
I've already read this post:
http://www.kriesi.at/support/topic/facebook-open-graph-protocol
but it doesn't really help me.
thanks

I have this code, which always worked for me with the standard article image.
$thumb = get_post_meta($post->ID,'_thumbnail_id',false);
$thumb = wp_get_attachment_image_src($thumb[0], false);
if ($thumb[0] == ""){
$thumb[0] = "http://.../image.jpg";
}
How can I modify it that it works with the new theme.
I know that I have to use "$slides[0]['slideshow_image']" but I don't know if I just have to replace $thumb[0] or every $thumb etc. I'm not very good in php.
Please help
Hey!
to get the post thumbnail in brightbox you can use the following code snippet:
$image = "";
$slides = avia_post_meta(get_the_ID(), 'slideshow', true);
if( $slides != "" && !empty( $slides[0]['slideshow_image'] ) )
{
$image = avia_image_by_id($slides[0]['slideshow_image'], 'widget', 'image');
}

It does recognize the photo if a user clicks on the send button or the like button
BUT
If I post the URL in facebook, it doesn't recognize a photo.
Try it for example with
http://treibhaus.co/opening
The facebook debugger says
Object at URL 'http://treibhaus.co/opening/' of type 'website' is invalid because the given value '<img src=' for property 'og:image:url' could not be parsed as type 'url'.
Kriesis code above will return the image with html tag, alt text, etc. and not the image url. Try following code instead:
$image = "";
$slides = avia_post_meta(get_the_ID(), 'slideshow', true);
if( $slides != "" && !empty( $slides[0]['slideshow_image'] ) )
{
$image = avia_image_by_id($slides[0]['slideshow_image'], 'widget', 'url');
}

hmm... very strange
The debugger doesn't show errors anymore and there's the right url in og:image, for example:
<meta property="og:image" content="http://treibhaus.co/wp-content/uploads/2012/02/header1-48x48.jpg" />
But facebook doesn't recognize the image when we type the URL in Facebook but it works if we press the send or like button in the article.
On all other blogs, where we also use kriesi templates, it works (but all the other blogs have the standard article picture)
Please help
But I think this is more a facebook issue now because we can't control which content is used by Facebook. If it works with the send or like button the og meta property seems to submit the correct content. I see no reason why Facebook can use it if you click on the button but then (on the other hand) it's ignored when it fetches the content automatically based on the website url...
