How to get the first image attached the post:

$images = get_children(array(
    'post_parent' => $post->ID,
    'post_type' => 'attachment',
    'post_mime_type' => 'image',
    'orderby' => 'ID',
    'order' => 'ASC'
  ));
  if($images){
    $ids = array_keys($images);
    $id = $ids[0];
    $url = wp_get_attachment_image_src($id);
  }else{
    /* no image */
  }

Upload your header image to ‘your theme folder/img’,
and write below code in your style.css

#header {
background:transparent url(img/your-header-image-filename.png) no-repeat center bottom;
height:160px; /* your header image height */
}

use

<?php
  endwhile;
  endif;
  wp_reset_query();
?>

instead of

<?php
  endif;
  wp_reset_query();
?>

WordPress 2.9.1

Create admin-script.js in theme folder and edit:

jQuery(document).ready(function($){
  $('.cat-checklist')
    .prepend(
      '<li><label class="selectit"><input value="1" type="checkbox" name="remove_categories" id="remove_categories"/> Remove Checked Categories</label></li>'
    );
});

functions.php:

function my_enqueue() {
  wp_enqueue_script('my_admin_script', get_bloginfo('template_url') . '/admin-script.js', array('jquery'), false, true);
}
add_action('admin_init', 'my_enqueue');

function my_bulk_edit($action, $result){
  if('bulk-posts' == $action && isset($_GET['remove_categories']) && isset($_GET['post_category'])){
    if(($_GET['action'] != -1 || $_GET['action2'] != -1 ) && ( isset($_GET['post']) || isset($_GET['ids']))){
      $post_ids = isset($_GET['post']) ? array_map( 'intval', (array) $_GET['post'] ) : explode(',', $_GET['ids']);
      $doaction = ($_GET['action'] != -1) ? $_GET['action'] : $_GET['action2'];
    }
    if('edit' == $doaction){
      if(isset($_GET['post_type']) && 'page' == $_GET['post_type']){
        if(! current_user_can('edit_pages'))
          wp_die( __('You are not allowed to edit pages.'));
      } else {
        if(! current_user_can( 'edit_posts' ))
          wp_die( __('You are not allowed to edit posts.'));
      }

      $post_IDs = array_map('intval', (array) $_GET['post']);
      if(is_array($_GET['post_category']) && ! empty($_GET['post_category'])){
        $remove_cats = array_map('absint', $_GET['post_category']);
        unset($_GET['post_category']);
        foreach($post_IDs as $post_ID){
          if(wp_check_post_lock($post_ID)) continue;
          $cats = (array) wp_get_post_categories($post_ID);
          $post_data['post_category'] = array_diff($cats, $remove_cats);
          $post_data['ID'] = $post_ID;
          wp_update_post($post_data);
        }
      }

}
add_action('check_admin_referer', 'my_bulk_edit', 10, 2);

Check ‘Remove Checked Categories’ and categories you want to remove!

Maybe, you click on “add image” and upload before new page is saved.
Usually, uploaded images have its parent. But I think your images have not their parent because of your clicking is too fast.

try this:
1. Open new post.
2. Enter the title.
3. Focus on content area.
4. wait.
5. Draft post is saved.
6. Click on “add image” and upload images.

If you kill the auto saving like:

function disableAutoSave(){
  wp_deregister_script('autosave');
}
add_action('wp_print_scripts', 'disableAutoSave');

You must fail. Enable auto saving.

oh, use
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
instead of
<li><?php the_permalink(); ?></li>
