How to show parent-gallery on image.php

How does 2 lines of code sound?

$gallery_shortcode = '[gallery id="' . intval( $post->post_parent ); . '"]';
print apply_filters( 'the_content', $gallery_shortcode );

sounds nice. but i’m not good in php. how do i put it into my image.php? still missin some <?php-stuff, right?

yep…

<?php
$gallery_shortcode = '[gallery id="' . intval( $post->post_parent ); . '"]';
print apply_filters( 'the_content', $gallery_shortcode );
?>

does not work ??

Sorry, there was a typo in the code I posted above. Try this:

<?php
$gallery_shortcode = '[gallery id="' . intval( $post->post_parent ) . '"]';
print apply_filters( 'the_content', $gallery_shortcode );
?>
