Can I add more photos to my project once I've started working on it?

You can add more photos to your project at any time while you're working on it. To do so:

1. Click on the project in your Library, and then click on Edit to open it.
2. Click the "Add Photos" button just above the photo tray, on the left side.
   
   
   
   
3. Select the photos you want to add and click "Finish".
