这绝对是可能的！！

好吧，这就是我所做的。。。

我的新循环如下所示：

    <?php $ids = array();?>
    <?php foreach(query_posts("category_name=photos&showposts=-1") as $post_blog): ?>
        <?php $url = wp_get_attachment_image_src( get_post_thumbnail_id($post_blog->ID), \'gallery-full\' ); ?>                    
        <?php $thumbs = wp_get_attachment_image_src( get_post_thumbnail_id($post_blog->ID), \'gallery-thumbnail\' ); ?>
        <?php list($width) = getimagesize($thumbs[0]); ?>
        <?php $ids[] = array("id_post" => $post_blog->ID, "width" => $width, \'url\' => $url[0], \'title\' => $post_blog->post_title);?>
    <?php endforeach; ?>
    <?php $page = isset($_GET[\'paged\'])?$_GET[\'paged\']:0;?>
    <?php $post_filters = get_posts_by_paged(2440, $ids, $page);?>
    <?php $count = $post_filters[\'count\']; ?>

    <div class="gallery">
        <?php if($post_filters):?>
            <?php foreach($post_filters[\'per_page\'] as $post_filter) : ?>
                <a href="<?php echo $post_filter[\'url\']; ?>" class="thickbox" title="<?php echo $post_filter[\'title\']; ?>" alt="<?php echo $post_filter[\'title\']; ?>"><?php echo get_the_post_thumbnail($post_filter[\'id_post\'], "gallery-thumbnail", array("title" => $post_filter[\'title\'], "alt" => $post_filter[\'title\'])); ?></a>
            <?php endforeach; ?>
        <div class="clear">
            <!-- -->
        </div>
        <?php endif; ?>
    </div>
    <hr />
    <?php if ( $prev = get_previous_posts_link("Previous Page") ) { ?>
        <div class="left">
            <div class="button"><?php echo $prev ?></div>
        </div>
    <?php } ?>
    <?php global $paged; ?>
        <?php if($paged == 0) {
            $paged = count($ids) > 20?1:0;
        }?>
    <?php if ( $next = get_next_posts_link("Next Page",$count)) { ?>
        <div class="right">
            <div class="button"><?php echo $next ?></div>
        </div>
    <?php } ?>

我的分页函数如下所示：

<?php 
function get_posts_by_paged($width_custom, $posts = array(), $page)
{
    $post_per_page = array();

    $widths = 0;
    $group = array();
    foreach($posts as $key => $post)
    {
        $widths = $widths+$post[\'width\'];
        if($widths > $width_custom){
            array_push($post_per_page, $group);

            //reset
            $group = array();
            $group[] = $post;
            $widths = $post[\'width\'];
        }else{
            $group[] = $post;
        }

        //recover last
        if(count($posts) == $key+1)
        {
            array_push($post_per_page, $group);                
        }
    }

    $page = $page>0?$page-1:$page;

return array("count" => count($post_per_page), "per_page" => $post_per_page[$page]);
}
?>

就这样！！对我来说，2440是个神奇的数字，但你可以把它改成你喜欢的任何数字。2440是所有图像的总宽度。。。如果需要更多行。。。增加数字，如果你想要更少，就减少数字。
