I'm looking for a way to enhance my image gallery by clicking on each image to reveal 4 related images without the need to create separate pages for each one. Any suggestions on how to achieve this efficiently?
Currently, I am utilizing an image gallery from: http://codepen.io/dimsemenov/pen/ZYbPJM
Although I've used Adobe InDesign to display four images in one PNG file due to space constraints, I believe there are more visually appealing and practical solutions available. Please advise.

This is the JavaScript code:
var initPhotoSwipeFromDOM = function(gallerySelector) {
// extracting slide data (url, title, size ...) from DOM elements
// (children of gallerySelector)
var parseThumbnailElements = function(el) {
var thumbElements = el.childNodes,
numNodes = thumbElements.length,
items = [],
figureEl,
linkEl,
size,
item;
for(var i = 0; i < numNodes; i++) {
figureEl = thumbElements[i]; // <figure> element
if(figureEl.nodeType !== 1) {
continue;
}
linkEl = figureEl.children[0]; // <a> element
size = linkEl.getAttribute('data-size').split('x');
item = {
src: linkEl.getAttribute('href'),
w: parseInt(size[0], 10),
h: parseInt(size[1], 10)
};
if(figureEl.children.length > 1) {
item.title = figureEl.children[1].innerHTML;
}
if(linkEl.children.length > 0) {
item.msrc = linkEl.children[0].getAttribute('src');
}
item.el = figureEl;
items.push(item);
}
return items;
};
var closest = function closest(el, fn) {
return el && ( fn(el) ? el : closest(el.parentNode, fn) );
};
var onThumbnailsClick = function(e) {
e = e || window.event;
e.preventDefault ? e.preventDefault() : e.returnValue = false;
var eTarget = e.target || e.srcElement;
var clickedListItem = closest(eTarget, function(el) {
return (el.tagName && el.tagName.toUpperCase() === 'FIGURE');
});
if(!clickedListItem) {
return;
}
var clickedGallery = clickedListItem.parentNode,
childNodes = clickedListItem.parentNode.childNodes,
numChildNodes = childNodes.length,
nodeIndex = 0,
index;
for (var i = 0; i < numChildNodes; i++) {
if(childNodes[i].nodeType !== 1) {
continue;
}
if(childNodes[i] === clickedListItem) {
index = nodeIndex;
break;
}
nodeIndex++;
}
if(index >= 0) {
openPhotoSwipe( index, clickedGallery );
}
return false;
};
var photoswipeParseHash = function() {
var hash = window.location.hash.substring(1),
params = {};
if(hash.length < 5) {
return params;
}
var vars = hash.split('&');
for (var i = 0; i < vars.length; i++) {
if(!vars[i]) {
continue;
}
var pair = vars[i].split('=');
if(pair.length < 2) {
continue;
}
params[pair[0]] = pair[1];
}
if(params.gid) {
params.gid = parseInt(params.gid, 10);
}
return params;
};
var openPhotoSwipe = function(index, galleryElement, disableAnimation, fromURL) {
var pswpElement = document.querySelectorAll('.pswp')[0],
gallery,
options,
items;
items = parseThumbnailElements(galleryElement);
options = {
galleryUID: galleryElement.getAttribute('data-pswp-uid'),
getThumbBoundsFn: function(index) {
var thumbnail = items[index].el.getElementsByTagName('img')[0],
pageYScroll = window.pageYOffset || document.documentElement.scrollTop,
rect = thumbnail.getBoundingClientRect();
return {x:rect.left, y:rect.top + pageYScroll, w:rect.width};
}
};
if(fromURL) {
if(options.galleryPIDs) {
for(var j = 0; j < items.length; j++) {
if(items[j].pid == index) {
options.index = j;
break;
}
}
} else {
options.index = parseInt(index, 10) - 1;
}
} else {
options.index = parseInt(index, 10);
}
if( isNaN(options.index) ) {
return;
}
if(disableAnimation) {
options.showAnimationDuration = 0;
}
gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options);
gallery.init();
};
var galleryElements = document.querySelectorAll( gallerySelector );
for(var i = 0, l = galleryElements.length; i < l; i++) {
galleryElements[i].setAttribute('data-pswp-uid', i+1);
galleryElements[i].onclick = onThumbnailsClick;
}
var hashData = photoswipeParseHash();
if(hashData.pid && hashData.gid) {
openPhotoSwipe( hashData.pid , galleryElements[ hashData.gid - 1 ], true, true );
}
};
initPhotoSwipeFromDOM('.my-gallery');
This is the 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;
}
Is there a simpler method to create this image gallery without relying on the aforementioned library?
I aim to achieve a design similar to this when clicking on an image: https://i.sstatic.net/gPZdS.png ^ The above design was created with Adobe Illustrator but it would be great to replicate it using HTML/CSS.
