In My Template I use this code to show the content gallery. The default size of the image size gallery is 51x51.
$gallery_shortcode = '[gallery id="' . intval( get_the_ID() ) . '" columns="5" width="200" height="100"]';
print apply_filters( 'the_content', $gallery_shortcode );
How can I change the width, height of the image in the template file.
Thanks.
