plugin that works for facebook comment/like thumbnails

[Jel]

tried a few and can't get any to work correctly - comment boxes/like buttons below wp posts appear obviously on fb, but with a totally random and unrelated thumbnail image. Anyone know of a plugin that actually pulls the image from the post liked/commented on?

you could make it pull it from the useraccount, which uses gravatar, just a matter of doing a custom comment callback with a custom comment form

yeah thing is though I want it to pull the pic from the actual post. fb seems to want to pick whichever pic on the page is closest to it's 180x180 or whatever dimension it is. There are a couple plugins that say they use the post pic, or assigned thumbnail/featured image but they don't always (in fact hardly ever).

<meta property="og:image" content="http://SITENAME/IMAGENAME" />

use that to tell facebook what image to use

oh thouhgt you meant thumbs for users for comments, if you wanna just select the thumbnail do the meta tag for fb.

that exact code? And where would I put that (if it is)? Seems that's a set image for the site as a whole? I want it to pull the specific pic from the specific post being shared/cpmmented on. Thanks

something like this in your functions.php file

function insert_image_src_rel_in_head() {
	global $post;
	if ( !is_singular()) //if it is not a post or a page
		return;
	if(!has_post_thumbnail( $post->ID )) { //the post does not have featured image, use a default image
		$default_image="http://example.com/image.jpg"; //replace this with a default image on your server or an image in your media library
		echo '<meta property="og:image" content="' . $default_image . '"/>';
	}
	else{
		$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
		echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
	}
	echo "
";
}
add_action( 'wp_head', 'insert_image_src_rel_in_head', 5 );

nope, still just pulls a random image off the page ><
