Can I change different logo for different pages in drupal

I want to change different logo for each different pages in drupal and I also want to hide logo for some pages too.How can I do that?I've already search possible answers and I didn't find any.

As was stated by MilanG, logo is rendered in your page template (default page.tpl.php or theme suggestion) using $logo variable. This variable is set in template_preprocess_page(), and the best way to change it is to use the same preprocess function in your theme:

function mytheme_preprocess_page(&$variables) {
  $logo_path = '/' . drupal_get_path('theme', 'mytheme') . '/logos/';
  // Alter logo under some conditions
  if ($first_condition) {
    $variables['logo'] = $logo_path . 'logo1.png';
  } elseif ($second_condition) {
    $variables['logo'] = $logo_path . 'logo2.png';
  } elseif ($third_condition) {
    // Hide logo. Your page.tpl.php must contain 
    // something like <?php if ($logo): ?>
    $variables['logo'] = null;
  }
  // etc.
}
