This plugin integrates PhotoSwipe to WordPress. All linked images in a post or page will be displayed using PhotoSwipe, regardless if they are part of a gallery or single images.
More about the original version of PhotoSwipe see here: <a href="http://photoswipe.com" rel="nofollow ugc">http://photoswipe.com</a>
You can also display EXIF data from supported image types.
As of version 4.0.0 this plugin requires at least WordPress 5.3 and PHP 7.0. Older PHP version will cause problems. In this case you have to upgrade your PHP version or ask your hoster to do so. Please note that WordPress itself also recommends at least PHP 7.4 – see <a href="https://wordpress.org/about/requirements/" rel="ugc">https://wordpress.org/about/requirements/</a>.
Please keep in mind: not the visible thumbnail is relevant, but only the image link. Images should always be linked to the file and not to the attachment page. Since version 5.6.1 there is an option to fix attachment links which can be enabled if needed – however this may slow down your website since then all links on a page will be checked if they are attachment links.

Simple Photoswipe extends WordPress’ built in gallery functionality and uses Dmitry Semenov’s awesome <a href="http://photoswipe.com/" rel="nofollow ugc">Photoswipe</a> gallery library.
You can customize some of Photoswipes options at Settings > Simple Photoswipe.
Important Note: In order to use Photoswipe zoom effect correclty you need to disable thumbnail cropping! 
By default your images will be cropped to proportional 150×150 thumbnails. I would reccomend to set a bigger thumbnail size (as shown in screenshot 4) and re-upload your images. In case you don’t want to re-upload your images I would recommend another plugin to automatically recrop your uploaded images.
