这两段代码可以实现显示独立的图片文件或者其他文件的缩略图。首先把第一段代码添加到functions.php中，然后你想在哪块显示就放在哪个模板文件中，想在文章中显示 就放在文章的模板中。
function get_attachment_files(){
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' => null,
'post_parent' => 0
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $post) {
setup_postdata($post);
the_attachment_link($post->ID);
}
}
}
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' => null,
'post_parent' => 0
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $post) {
setup_postdata($post);
the_attachment_link($post->ID);
}
}
}
