First, click the 
button in the upper, left-hand corner and you will find yourself on the editing page. Click the 
button in the editing menu.This is where you can find the storyboard of your book. Here, you can easily organize your story by dragging photos from one page to another, while having an overview of the whole book. You can also control the size of your pictures:
- Click on each picture individually:
stands for full size (1 photo per page), 
for double size (2 photos per page) and 
for 1/4 size (4 photos per page). - Click the “Resize All” button, that changes the size of all the pictures in your book.
- The “Mix it!” button randomly assigns sizes for your photos, try it to see how your pictures can appear in the book!
- Keep in mind, that 1/4 sized pictures have rectangular shape and your photos will be cropped in order to fit the rectangle. Choose the 1/4 sized pictures carefully! For instance, it is not recommended to put pictures with a portrait orientation 4 per page.
Keep in mind that titles are hidden on 1/4 sized pictures: there is just not enough space for them!
Don't forget to click the “Save” 
button, otherwise your changes will be discarded.
