WordPress image gallery
WordPress comes with built-in image gallery functionality. That means without using any additional plugin, you can create WordPress image gallery. Using WordPress, it is possible to add several images in the post and we can show them as a WordPress image gallery.
To create WordPress image gallery in a new post, go to your WordPress admin area >> Posts > Add New.
Click the “Add Media” button in the WYSIWYG editor menu and upload the images that will be shown in the gallery.

When you are ready, click Save all changes.
A Gallery tab will appear and when you click it, you will be able to arrange your images and set the gallery settings.
Select the images from your media library and click on “Create a new gallery”

Publish your post and you will be able to see your WordPress image gallery in the new post on your WordPress blog.
