It's important to note that when you delete photos from Google Photos, they will also be removed from your Google account and any device that is synced with your account. Be sure to double-check that you want to delete the photos before confirming the action. Additionally, deleted photos will be moved to the "Trash" or "Bin" folder where they will remain for 60 days before being permanently deleted. You can manually empty the Trash/Bin to permanently delete the photos if needed.
