To add a photo gallery to a page:
1) Go to Publish > Pages and pick out the page you’d like to add the gallery to.
2) Click on the page to edit it.
3) Go down to the content box on that page and place your mouse/curser where you’d like the photo gallery to be placed.
4) On the content box toolbar select the “Add Media” button (just as you would if you were adding an image) and then click on the “Choose Gallery” tab.
5) Click on the gallery you’d like to use and click “add gallery”.
