Once you've selected your photos and they've downloaded to your Premium Photo Prints subscription, you can edit them before sending them to print.
The Edit print page lets you:
Crop
Add a border
Replace with a new image
To make any of these edits, tap into a photo. If you tap Crop, you can rotate a photo by tapping Rotate or change its orientation by tapping Change orientation.
Once you've made your edits, tap Save.
Under the Border option, you can print a photo with a border or as Full, which means the image covers the entire print.
Border vs. Full:
On this page, you can also apply Full or Border to every print in the set by tapping Apply.
To choose a different photo, tap Replace.
Choose a new photo from your Camera Roll or Google Photos, then tap Continue with 1 photo at the bottom of the screen.
The photo is now included in your set.
To print a photo more than once, you can upload it again, or increase its quantity here:
Tap the + sign to add more copies of that print, then tap Done in the upper right-hand corner.
Each print over 10 in a Print Set costs an additional $0.90. You'll see this at checkout when you send a new Print Set to print.
