To be added to your cookbook, all of your photo files should be in a JPEG format. You can tell by their file extension ".jpg". If you are scanning or editing images, they should also have a resolution of 300dpi. You'll see a resolution warning as you edit your book if the resolution of your image is too low to print clearly.
You can upload photos from any page where a photo can be placed. You can add photos to certain page layouts, including the title page, section dividers, and some recipe pages and story pages. You can also add your own images to the front and back cover. To upload a photo, click the "edit" button and head to the "Picture" tab*.
You'll see the "Add Photos" Button. Click on it and choose either "computer" or "Facebook." If you choose "computer," a file explorer window comes up so you can locate your files on your computer. If you choose "Facebook," you will be asked to sign into Facebook to choose your photos.
Once the uploading has finished, you should see your picture(s) appear in your photo gallery. Your photo's title will be auto-populated, but you can edit the title by clicking on the text, typing a new title, and clicking the blue checkmark.
Using the search bar, you can search through all of your photos in your personal gallery as well as millions of stock photos.
*Don't see a picture tab? You'll need to change the page layout to one that allows a photo. Go to the "layout" tab to see your options.
