How do I upload photos from Google Photos?
In addition to using photos from your computer or mobile devices, Collage.com has made it easy to add images from Google Photos.
Connecting Google Photos
All of Collage.com's upload options can be found by clicking to the left of an open project or below the project for mobile users. (You'd click on book or calendar projects).
You'd then click "Google Photos" from the list of options to be prompted to login to your Google Photos account.
Login with your Google Photos credentials, and then click "Allow" when prompted to allow Collage access.
Then, your Google Photos uploads will appear in folders for you to add to your project.
Disconnecting Google Photos
To disconnect Collage from Google Photos, go to myaccount.google.com/security and scroll to the "Apps with account access" section and click "Manage Apps."
Select Collage.com from the app list and then click "Remove Access" to revoke sharing with Collage.com.
