When you upload photos to your PastBook, the pop-up window will ask you if you want to add the photos as full page (one photo per page) or minimized (2 photos per page).
You can also manually expand or minimize each individual photo. Click the 
button in the upper, left-hand corner and find yourself on the editing page. Now you can change the size of the photos by clicking on each photo and clicking
or 
.
Another way to play with the sizes of your pictures is to 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 a rectangular shape and your photos will be cropped in order to fit the rectangle. Choose the 1/4 sized pictures carefully!
Don't forget to click the 
button, otherwise your changes will be discarded.
