You are looking code to add a column next to short link. It’s pretty much simple. There are two things here. You can add it for specific post type or common to all the post types you have.
// add a thumbnail column to the edit posts screen
function kv_post_thumbnail_column($cols) {
$cols['thumbnail'] = __('Thumbnail', '1stopwebsolution');
return $cols;
}
add_filter('manage_posts_columns', 'kv_post_thumbnail_column');
// go get the attached images for the logo and thumbnail columns
function kv_thumbnail_value($column_name, $post_id) {
if (('thumbnail' == $column_name) || ('logo' == $column_name)) {
if (has_post_thumbnail($post_id)) echo get_the_post_thumbnail($post_id, array( 71, 61));
}
}
add_action('manage_posts_custom_column', 'kv_thumbnail_value', 10, 2);
This will add a Thumbnail column next at last of all the post type’s listing table.
