In Template menu,
Open functions.php file. Just paste the following code.

//Custom CSS option panel
add_action('admin_menu', 'custom_css_hooks');
add_action('save_post', 'save_custom_css');
function custom_css_hooks() {
    add_meta_box('custom_css', 'Custom CSS', 'custom_css_input', 'post', 'normal', 'high');
    add_meta_box('custom_css', 'Custom CSS', 'custom_css_input', 'page', 'normal', 'high');
function custom_css_input() {
    global $post;
    echo '<input type="hidden" name="custom_css_noncename" id="custom_css_noncename" value="'.wp_create_nonce('custom-css').'" />';
    echo '<textarea name="custom_css" id="custom_css" rows="5" cols="30" style="width:100%;">'.get_post_meta($post->ID,'_custom_css',true).'</textarea>';
function save_custom_css($post_id) {
    if (!wp_verify_nonce($_POST['custom_css_noncename'], 'custom-css')) return $post_id;
    if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return $post_id;
    $custom_css = $_POST['custom_css'];
    update_post_meta($post_id, '_custom_css', $custom_css);
function insert_custom_css() {
    if (is_page() || is_single()) {
        if (have_posts()) : while (have_posts()) : the_post();
            echo '<style type="text/css">'.get_post_meta(get_the_ID(), '_custom_css', true).'</style>';
        endwhile; endif;

Step 2: Next create CSS sprites with combination of images and its location in CSS. I am already written a post to create CSS sprites.
