The functions.php file in your active theme also needs to have add_theme_support( 'post-thumbnails' );
See this page
already done… still nothing
That code in site source look that way:
<link rel=”image_src” href=”” / >
I don’t think it will work in the <head> section as the_post_thumbnail() outputs image markup – not the image src. Why exactly do you want to add a post thumb to the head of your pages?
I assumed that meant header.
That code; <link rel=”image_src” href=”URL HERE” / > will give Facebook a standard 1 image for url…
It work for main <head>, but I want for every post another image.
no…
When you add post in Facebook wall, Facebook search images or find that code “image_src” and add it to one option for image url. I can do it for all site by add that code to normal <head> in header.php but All in One Seo allowes me to add another code to each post page <head>. And in that head I need to attach the code URL from thumbnail to do that icon.
I would also like to do this.
With the new Facebook Open Graph stuff, you can define a thumbnail for that page in your <head> of the form
<meta property="og:image" content="[image url]"/>.
I would like to use
<meta property="og:image" content="<?php the_post_thumbnail(); ?>"/>
but since this is outside the loop, the tag returns nothing.
Is there a way to get this to work outside the loop?
Thanks
anyone managed to make this work?
hope this helps, found it on google
