Generating the ogp tags in theme

Question

I use to generate the ogp tags in themes I code but this commercial one is beyond my knowledge. The client want to share a page but any image option shows up.

Instead of a taxonomy-name.php template file, this theme rely on a page templates, where user choose the category/taxonomy to display the gallery from. Problem is: I can't get the attachments as the gallery renders after the query, I do will ask the theme autor to implement this but right now I need to fix this some way.

Thanks for any help

If it is a page the global post object is already set when wp_head fires. But you have to get the data for this page with custom code.

Pseudo code:

add_action ( 'wp_head', 'wpse_58539_get_ogp' );

function wpse_58539_get_ogp()
{
    if ( ! is_page_template( 'your-template-name' ) )
    {
        return;
    }

    $page = get_post( $GLOBALS['post'] );

    // Inspect the page meta data to find the taxonomy and the images.
    // print the OGP data

    return;
}
