最近，我问了一个关于如何从所有帖子中获取所有图片的问题，我得到了一个有效的答案，但不幸的是，代码也得到了帖子thumnbnails，我没有找到限制查询图片数量的方法。

My last question is here.

谢谢

<?php
$query = new WP_Query( array( \'post_type\' => \'post\', \'posts_per_page\' => -1 ) );
if( $query->have_posts() ){
while($query->have_posts()){
$query->the_post();
$thumb_ID = get_post_thumbnail_id( $post->ID );
$image_query = new WP_Query( array( \'post_type\' => \'attachment\', \'exclude\' => $thumbID, \'post_status\' => \'inherit\', \'post_mime_type\' => \'image\', \'posts_per_page\' => -1, \'post_parent\' => get_the_ID() ) );
while( $image_query->have_posts() ) {
$image_query->the_post();
echo \'<dl class="gallery-item"><dt class="gallery-icon"><a rel="shadowbox[sbalbum-1];player=img;" href="\' , the_permalink() , \'">\', wp_get_attachment_image( get_the_ID() ) , \'</a></dt></dl>\';
}
}
}
?>

在image\\u查询中更改posts\\u per\\u page参数的数量对显示的附件数量没有影响。

在@Bainternet的帮助下，我产生了以下工作代码：

<?php
$image_count = 0;
$max_images = of_get_option(\'thumbs_number\');
$Posts = new WP_Query();
$Posts->query(\'post_type=post&post_status=publish&posts_per_page=-1\');
    while ($Posts->have_posts()) : $Posts->the_post();    
    $args = array(
    \'post_type\' => \'attachment\',
    \'numberposts\' => -1,
    \'post_status\' => null,
    \'post_parent\' => $post->ID,
    \'exclude\' => get_post_thumbnail_id($id)
    );

$attachments = get_posts( $args );
    if ( $attachments ) {
        foreach ( $attachments as $attachment ) {
            if ($image_count < $max_images){
echo \'<dl class="gallery-item"><dt class="gallery-icon"><a rel="shadowbox[sbalbum-1];player=img;" href="\' , the_permalink() , \'">\';
echo wp_get_attachment_link( $attachment->ID, \'footer_thumbs\' );
echo \'</a></dt></dl>\';
$image_count = $image_count + 1;
        }
    }
}
endwhile;?>

$image_count = 0;
$max_images = 10;  //set this to the max number of images you want.
$ids = get_posts( array( \'post_type\' => \'post\', \'posts_per_page\' => -1 ,\'fields\' =>\'ids\') );
if (count($ids) > 0){
    foreach ($ids as $id){
        while ($image_count < $max_images){
            $args = array(
                \'post_type\'   => \'attachment\',
                \'numberposts\' => -1,
                \'post_status\' => null,
                \'post_parent\' => $id,
                \'exclude\'     => get_post_thumbnail_id($id)
            );
            $attachments = get_posts( $args );
            if ( $attachments ) {
                foreach ( $attachments as $attachment ) {
                    if ($image_count < $max_images){
                        echo \'<dl class="gallery-item">
                            <dt class="gallery-icon">
                                <a rel="shadowbox[sbalbum-1];player=img;" href="\' . get_permalink($attachment->ID) . \'">\'. wp_get_attachment_image( $attachment->ID ) . \'</a>
                            </dt>
                         </dl>\';
                         $image_count = $image_count + 1;
                    }
                }
            }
        }
    }
