You've put together a lovely layout, but now you'd like to move one of your photo pages to a different spot. While it's not possible to simply drag a full page to a new position, there's a simple trick that gets you the same result.
As you can see in the images below, you can add a new page at the spot where you'd like the photo page to appear, and then drag the photos into the same layout they had on the original page. This way, you can effectively move a photo page to any other spot in your Travel Book.
Note: This can only be done per step. It is not possible to move photos to another step in the editor.
