Covers are a special page type available when building an album.
To create a cover, go to the Editor tab, and choose Cover.
The cover is not included in the Book or Page view of your project.
Edit the cover in the same manner as a Page.
Covers display extra guidelines, depending on your album settings. These include margins for the spine.
If you have set up a custom product for your album, be sure to ask the manufacturer about cover options and sizes.
Some manufacturers do not allow custom-printed covers, but use stock covers (possibly embossed) rather than a printed photo option.
Some manufacturers may have multiple cover dimensions for albums with different page ranges. The spine will grow larger as the number of pages increases, so it is important to get the right dimensions before submitting your finalized project for printing.
