Needed Markup
In consider to work, a link need to have the class lightbox and some data- attributes. If an image is inside the link, this image is used for small thumbnail for an faster UI experience.
data-title
This attribute is used for the caption in the lightbox. If this is not given, it search inside the link for a figcaption and uses this as caption. This is also a great way if you want to have HTML some markup inside your caption.
data-size
The size of the image to enlarge, e.g. 2560x1200. Example:
<a class="lightbox" data-size="2560x1200" href="path/to/image.jpg">...</a>An alternative Markup would be:
<a
class="lightbox"
data-width="2560"
data-height="1200"
href="path/to/image.jpg"
>...</a
>data-ratio and data-ratio-image
If it not possible the get the size of the enlarged image (e.g. because the image is set to async), you can pass also data-ratio or data-ratio-image. Be aware, that this works best if you also pass the data-width (for zooming purposes). data-ratio-image can be a small version of the image (e.g. 100px wide). If this is given, it tries to get the dimensions and calculate the ratio from the filename. If this is not possible, the image get loaded and the ratio is calculated with naturalWidth and naturalHeight. After the first time an asnc picture is loaded, Neos replace the path width the filename where the ratio can be calculated without downloading the image.
data-href-webp
If you want to open an image with the webp format you can pass it here (if the browser supports it)

Installation
Most of the time you have to make small adjustments to a package (e.g.
configuration in Settings.yaml). Because of that, it is important to add the
corresponding package to the composer from your theme package. Mostly this is
the site packages located under Packages/Sites/. To install it correctly go to
your theme package (e.g.Packages/Sites/Foo.Bar) and run following command:
composer require jonnitto/photoswipe --no-updateTo install the package under Neos 2.* you have to enter
composer require "jonnitto/photoswipe:^0.2" --no-updateThe --no-update command prevent the automatic update of the dependencies.
After the package was added to your theme composer.json, go back to the root
of the Neos installation and run composer update. Et voilà! Your desired
package is now installed correctly.
