How to create a Full Page Slide Show in WordPress.com

Create a new page (or post) which will hold the slide show itself.
Using the Add Media button, select a group of photos for the slide show and make it a GALLERY. Don’t change any of the options – the defaults are fine.
An example is below – it isn’t a full page slide show but if you click on one of the images, you will jump into a slide show. The first image in this one jumps to the URL https://rosalindannmartin.com/2016/03/06/how-to-create-a-full-page-slide-show-in-wordpress-com/#jp-carousel-535 – THAT is the URL which is the full page slide show and you can use that anywhere in your website that you want to hot-link to this particular slide show.
