【问题描述】：
我有一个图片库，我想点击每张图片以显示 4 张相关图片。如果不为每个图像创建一个全新的页面来显示其相关图像，那么最好的方法是什么？
我将它用于图片库： http://codepen.io/dimsemenov/pen/ZYbPJM
目前我使用 Adobe InDesign 在一个 png 文件中显示四个图像（由于空间限制），但当然还有更美观和更智能的方式。请提出解决方案。

这是 js：

// create slide object
item = {
src: linkEl.getAttribute('href'),
w: parseInt(size[0], 10),

// <img> thumbnail element, retrieving thumbnail url
item.msrc = linkEl.children[0].getAttribute('src');

item.el = figureEl; // save link to element for getThumbBoundsFn
items.push(item);

var openPhotoSwipe = function(index, galleryElement, disableAnimation, fromURL) {
var pswpElement = document.querySelectorAll('.pswp')[0],
gallery,
options,

var galleryElements = document.querySelectorAll( gallerySelector );
for(var i = 0, l = galleryElements.length; i < l; i++) {

galleryElements[i].onclick = onThumbnailsClick;
}
// Parse URL and open gallery if it contains #&pid=3&gid=1
var hashData = photoswipeParseHash();
if(hashData.pid && hashData.gid) {
openPhotoSwipe( hashData.pid , galleryElements[ hashData.gid - 1 ], true, true );
}
};
// execute above function
initPhotoSwipeFromDOM('.my-gallery');
这是 CSS：
.my-gallery {
width: 100%;
float: left;
}
.my-gallery img {
width: 200px;
height: 200px;
display: block;
}
.my-gallery figure {
display: block;
float: left;
margin: 0px 15px 20px 0;
border: 3px solid #000;
}
.my-gallery figcaption {
display: none;
}
还有没有更简单的方法来获得这个图片库而不使用上面的这个库？
基本上，当您单击图像时，我想显示如下内容： ^ 以上是用 adobe illustrator 制作的，如果用 html/css 制作就好了。

嘿，如果你使用类似这样的 CSS Modal 并用你的 4 张图片填充它会怎样？ codepen.io/ohnoitsaustin/pen/zGmJjz
