我有一个画廊，里面有不同尺寸的图片。有些是纵向的，有些是横向的。使用最新版本的 JQuery 和 Supersized，是否可以：
a）以#supersized ul的100％按比例显示我的所有图像，而不会切断我的横向格式图像，并且在调整窗口大小时所有图像仍按比例调整大小？
b) 将这些图像水平居中，随着它们变小，水平和垂直居中？
或者是否有其他插件我们可以这是我对使用 Wordpress 循环的 Supersized 的调用：
jQuery(document).ready(function($){
$.supersized({

$category = get_queried_object();
$cid = $category->term_id;
$args = array('post_type'=>'photo', 'cat'=>$cid);
$i = 0;
$posts = query_posts( $args );
$count = count($posts) - 1;
$q = new WP_Query( $args );
if ($q->have_posts()) : while ($q->have_posts()) : $q->the_post();
$post_thumbnail_id = get_post_thumbnail_id();
$featured_src = wp_get_attachment_image_src( $post_thumbnail_id, 'square' );
if ($i != $count) {
echo "{ image : '". $featured_src[0] ."', title :''},";
} else {
echo "{ image : '". $featured_src[0] ."', title :''}";
}
$i++;

});

这是我的 CSS（特定于类别图像，因为我在页面的其他地方有一个实际的全屏 Supersized）：
