There is no direct integration between Google Drive and Google Photos, but there are a few workarounds that you can use to access your photos from Drive.
The easiest way to do this is to simply upload the photos you want to access from Google Photos to Google Drive. You can do this by opening the Google Photos app and selecting the photos you want to upload. Then, tap the Share icon and select Drive from the list of options.
Another way to access your photos from Drive is to use the Google Drive app for iOS or Android. Once you have the app installed, open it and tap the (+) icon. Select Upload from the menu and then choose the photos you want to upload from your device.
If you want to be able to view your Google Photos in Drive without uploading them, you can use a third-party service like PicBackMan. This service lets you connect your Google Photos and Drive accounts and then automatically syncs your photos between the two platforms.
