我想更改jetpack默认为空。og上的jpg atribute：图像。我读了一些关于这门学科的文章，但没有真正帮助我。以下是一些尝试：

/**
 * Override the default OpenGraph tags
 */
add_filter( \'jetpack_open_graph_tags\', function( $tags ) {
    $tags[\'twitter:site\'] = \'@ourhandle\';
    $tags[\'twitter:creator\'] = \'@ourhandle\';
    $tags[\'og:site_name\'] = \'Our Site Name\';


// the og:image key defaults to the featured image. if the value is
// not set, define it as an array. if the value is set, assume it is
// the featured image (or has been previously filtered)
if ( ! isset( $tags[\'og:image\'] ) ) {
    $tags[\'og:image\'] = array();
}
$tags[\'og:image\'] = (array)$tags[\'og:image\'];

if ( is_a_particular_blog() ) {
    $blog = custom_get_blog();
    $tags[\'og:image\'][] = custom_the_term_image_src( $blog->term_taxonomy_id );
} else {
    foreach ( get_coauthors() as $coauthor ) {
        $tags[\'og:image\'][] = custom_get_coauthor_avatar_uri( $coauthor->ID, true );
    }
}
$tags[\'og:image\'][] = \'http://static.oursite.org/images/oursite_opengraph_360x185.png\';
return $tags;
} );



function fix_jp_og_bugs ($og_tags)
{
    $og_tags[\'twitter:site\'] = \'@laszlop\';

    if  (0 == strcmp ($og_tags[\'og:image\'],
        "https://s0.wp.com/i/blank.jpg")
    {
        unset ($og_tags[\'og:image\']);
    }

    return $og_tags;
}

add_filter (\'jetpack_open_graph_tags\', \'fix_jp_og_bugs\', 11);

所以我想在主页上看到这个元标签：

<meta property="og:image" content="http://www.neocsatblog.mblx.hu/wp-content/uploads/2013/04/cropped-jobbbföld-maszk-21.png" />

而不是这个：

<meta property="og:image" content="https://s0.wp.com/i/blank.jpg" />

我将Ifeature主题与最新的wordpress和jetpack插件结合使用<我的网站是：
http://neocsatblog.mblx.hu/

add_filter( \'jetpack_open_graph_image_default\', \'example_change_default_image\' );
function example_change_default_image( $image ) {
    return \'https://s0.wp.com/i/blank.jpg\';
}

function fb_home_image( $tags ) {
    if ( is_home() || is_front_page() ) {
        // Remove the default blank image added by Jetpack
        unset( $tags[\'og:image\'] );

        $fb_home_img = \'YOUR_IMAGE_URL\';
        $tags[\'og:image\'] = esc_url( $fb_home_img );
    }
    return $tags;
}
add_filter( \'jetpack_open_graph_tags\', \'fb_home_image\' );

function custom_jetpack_default_image() {
    return \'YOUR_IMAGE_URL\';
}
add_filter( \'jetpack_open_graph_image_default\', \'custom_jetpack_default_image\' );
