Add featured image to custom post type…

Hi,

I have used a function to create a post type but the featured image does not appear in the editor. Could you please help me with this?

Here is the code used to create the post type:

// Register Custom Post Types
add_action(‘init’, ‘register_custom_posts_init’);
function register_custom_posts_init() {
// Register Members
$members_labels = array(
‘name’ => ‘Members’,
‘singular_name’ => ‘Member’,
‘add_new’ => ‘Add New’,
‘add_new_item’ => ‘Add New Member’,
‘edit_item’ => ‘Edit Member’,
‘new_item’ => ‘New Member’,
‘all_items’ => ‘All Members’,
‘view_item’ => ‘View Member’,
‘search_items’ => ‘Search Members’,
‘not_found’ => ‘No members found’,
‘not_found_in_trash’ => ‘No members found in the Trash’,
‘parent_item_colon’ => ”,
‘menu_name’ => ‘POD Members’

);
$members_args = array(
‘labels’ => $members_labels,
‘public’ => true,
‘capability_type’ => ‘post’,
‘has_archive’ => true,
‘supports’ => array( ‘title’, ‘editor’, ‘excerpt’, ‘thumbnail’, ‘revisions’ )
);
register_post_type(‘members’, $members_args);
}
