By integrating these features, Easy Post Gallery offers a user-friendly solution for managing and displaying image galleries across various post types in WordPress.

Easy Post Gallery

zitscher

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.
