    <?php
    /**
    * TwentyTen functions and definitions
    *
    * Sets up the theme and provides some helper functions. Some helper functions
    * are used in the theme as custom template tags. Others are attached to action and
    * filter hooks in WordPress to change core functionality.
    *
    * The first function, twentyten_setup(), sets up the theme by registering support
    * for various features in WordPress, such as post thumbnails, navigation menus, and the like.
    *
    * When using a child theme (see http://codex.wordpress.org/Theme_Development and
    * http://codex.wordpress.org/Child_Themes), you can override certain functions
    * (those wrapped in a function_exists() call) by defining them first in your child theme’s
    * functions.php file. The child theme’s functions.php file is included before the parent
    * theme’s file, so the child theme functions would be used.
    *
    * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
    * to a filter or action hook. The hook can be removed by using remove_action() or
    * remove_filter() and you can attach your own function to the hook.
    *
    * We can remove the parent theme’s hook only after it is attached, which means we need to
    * wait until setting up the child theme:
    *
    *
    * add_action( 'after_setup_theme', 'my_child_theme_setup' );
    * function my_child_theme_setup() {
    * // We are providing our own filter for excerpt_length (or using the unfiltered value)
    * remove_filter( 'excerpt_length', 'twentyten_excerpt_length' );
    * ...
    * }
    *

    *
    * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.

    追記です。固定ページ編集画面のアイキャッチ画像には表示されます。

    hikoshimanさん、こんにちは。

    アイキャッチ画像が表示されるためには、画像のサイズが 940px * 250px 以上のものが必要となっています。
    この条件は満たしていますか?

    twenty tenと言うのは、テーマの名前ですよね。
    私自身twenty tenテーマを使ったことは無いですが、
    アイキャッチ画像には対応してると思うので、テンプレート自体の表示設定ではないでしょうか。

    また、テンプレートをコード弄ってカスタマイズしているのであれば、
    <?php the_post_thumbnail(); ?>
    で表示できるかと思います。

    the_post_thumbnail

    少し古いですがわかりやすそうなページ見つけたので、追記。
    twenty-tenテーマをカスタマイズ
