Gallery Post Format
Progress also uses the same touch enabled slideshow on the home page to power the gallery image format. It’s a great way to show off your images. Just upload the images you’d like to use on the page/post where you’d like to use the slideshow. You don’t even have to insert it into the post for them to be included in the gallery slideshow.
You can still use the original gallery that’s included in WordPress if you’d rather. This just makes it simple to add a slideshow at the top of any page or post.
