Different header image 'Home' and Pages

Question

I want to use two images in the header. In the home page and single.php is the image I've uploaded in the panel (named logo.png). For pages I want use the image 'logopage.png' (directory: /images/logopage.png).

Just the image I'm using in home page is working. In the pages nothing appears.

How can I do that?

Ps.: The code I'm trying to use:

function.php:

add_theme_support( 'custom-header', array(
  'default-image' => get_template_directory_uri() . '/images/logo.png',
  'random-default'         => false,
  'width'                  => 1050,
  'height'                 => 100,
  'flex-height'            => true,
  'flex-width'             => true,
  'default-text-color'     => '',
  'header-text'            => false,
  'uploads'                => true,
  'wp-head-callback'       => '',
  'admin-head-callback'    => '',
  'admin-preview-callback' => '',
));

In the header.php:

  <?php
  if ( is_home() ) echo theme_heading();
  if ( is_single() ) echo theme_heading();
      elseif ( is_page() ) get_template_directory_uri() . '/images/logopage.png';
  ?>

Sorry my english :X

I got it!

<?php if (  (is_home()) || (is_single())  ) { ?>
<?php echo theme_heading(); ?>
<?php } elseif (is_page()) { ?>
<img src="<?php echo get_stylesheet_directory_uri() ?>/images/logopage.png" />
<?php } ?>

Thanks to everyone!
