Set up HTML Markup
You can make each image separate lightbox box or gallery in jekyll. You just have to gallery and children. First thing you have to do in _layout just add main tag or you can use div with id or class.And for image to add you can do that using just markdown in jekyll thats it.
[](assets/img-2500.jpg)
The markdown will generate the following html markup , thats what we want.
<a href="assets/img-2500.jpg"><img src="assets/img-200.jpg" alt="Example Image"></a>
Basic JS
Now in your script just change gallery: '#main' according to your layout. To add class you can just put '.main' and for html tag 'main'.
// Include Lightbox
import PhotoSwipeLightbox from '/photoswipe/photoswipe-lightbox.esm.js';
const lightbox = new PhotoSwipeLightbox({
// select all images in a post or page
gallery: '#main',
// Elements within gallery only anchor with img only
children: 'a:has(img)', //avoid other links
// setup PhotoSwipe Core dynamic import
pswpModule: () => import('/photoswipe/photoswipe.esm.js')
});
lightbox.init();
<script src="//cdnjs.cloudflare.com/ajax/libs/photoswipe/5.3.7/umd/photoswipe-lightbox.umd.min.js" async></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/photoswipe/5.3.7/umd/photoswipe.umd.min.js" async></script>
<link href="//cdnjs.cloudflare.com/ajax/libs/photoswipe/5.3.7/photoswipe.min.css" rel="stylesheet" />
<script>
function initPhotoSwipe() {
let customOptions = {};
try {
const data = `{{ site.photo_previewer }}`.replaceAll("=>", ":");
customOptions = JSON.parse(data);
} catch (e) {
console.info("Invalid custom photo previewer options! " + e.message);
}
// Define object and gallery options
const options = Object.assign(
{
gallery: "main",
children: "a.photo-swipe",
photo_scale: 2,
// dynamic import is not supported in UMD version
pswpModule: PhotoSwipe,
},
customOptions
);
const galleryEl = document.querySelector(options.gallery);
if (!galleryEl) {
return;
}
const imgEls = [];
const els = galleryEl.querySelectorAll("img:not(.emoji)");
els.forEach((el) => {
if (el.src.trim() == "") {
return;
}
if (!imgEls.includes(el)) {
imgEls.push(el);
}
});
if (imgEls.length === 0) {
return;
}
imgEls.forEach((imgEl) => {
imgEl.outerHTML = `
<a class="photo-swipe"
href="${imgEl.src}"
data-pswp-width="${Math.max(imgEl.naturalWidth, imgEl.width) * options.photo_scale
}"
data-pswp-height="${Math.max(imgEl.naturalHeight, imgEl.height) * options.photo_scale
}"
data-pswp-caption="${imgEl.getAttribute("caption") || imgEl.alt}"
target="_blank">
${imgEl.outerHTML}
</a>`;
});
// Initialize PhotoSwipe 5
var lightbox = new PhotoSwipeLightbox(options);
lightbox.init();
}
window.addEventListener("load", initPhotoSwipe);
</script>
