7.1 How to create a group of images / gallery that can be used on multiple pages?

Site URL: https://fortunemeadows.squarespace.com

Help! I have watched several videos and read the 7.1 knowledge base. However it's still not clear to me how I can create a group of images or gallery that can be inserted in several locations throughout the site. For example, the website I am working on is for a dog breeder. We would like to create a group of images of the male dogs she owns and include those images on several different pages of the site. I don't want to have to create a gallery section and upload the pictures every time. From what I have read, I should be able to create a gallery of images and show that gallery on several different pages but the only instructions I have found related to this are for version 7.0 as opposed to 7.1. How can I do this in 7.1? Thanks!

This article will tell you want you can duplicate in 7.1. and how to do it.  I suggest you build the content in your unlinked section, as you master so to speak and copy from there.
