You can add Google Photos to your frame using the Google Photos integration in the Aura App. When you open the Aura App, you'll see the option to add your Google Photos account under the Smart Albums section on the Photos tab of the Aura app. Tap here and enter your Gmail address and password. Once this is complete you'll have access to all your Google Photos.
Please note that there is a limit to the number of Google Photos per album we are able to import to the Aura App. The max is 10,000 photos per album. Additionally, any shared Google Albums will not appear in the Aura App. This is a limitation in how the Google Photos application integrates with our app, and unfortunately we can't adjust this to allow for unlimited photos to be synced using Google Photos. If you have more than 10,000 photos in a Google Photos album, we suggest you break your photos into multiple albums with fewer photos than 10,000 each.
