Wordpress使用条件标签发布不同的徽标

Question

I like to show different logo on two different page but keep the original logo on front page and the rest of the site. So I try with wordpress conditional tag but It doesn't work. Someone can help me?

Thank you.

<?php if ( ! is_front_page() ) {?>
<img class="logo-top" src="image1" alt="image1">
<?php } ?>

<?php elseif ( ! is_page(157) ) {?>
<img class="logo-top" src="image2" alt="image2">
<?php } ?>

<?php elseif ( ! is_page(157) ) {?>
<img class="logo-top" src="image3" alt="image3">
<?php } ?>

<?php else ( ) ) {?>
<img class="logo-top" src="image1" alt="image1">
<?php } ?>

<?php endif; ?>

The correct syntax is:

<?php if (!is_front_page()) { ?>
    <img class="logo-top" src="image1" alt="image1">
<?php } elseif (!is_page(157) ) { ?>
    <img class="logo-top" src="image2" alt="image2">
<?php } elseif (!is_page(157) ) { ?> <!-- Why is this the same id? Never will be executed  -->
    <img class="logo-top" src="image3" alt="image3">
<?php } else { ?>
    <img class="logo-top" src="image1" alt="image1">
<?php }
