Hello Graeme. To install Google Photos on your desktop, the most effective method is to use it as a Progressive Web App through Chrome or Microsoft Edge. You can visit photos.google.com, then click the install icon in the browser’s address bar and confirm the installation. This creates a standalone app-like shortcut on your desktop that runs independently of the browser, offering quick access to your photo library. For alternate option, if your goal is to automatically back up photos from your desktop to Google Photos, you can download the Google Drive desktop app, enable photo backup during setup, and select folders to sync. This ensures your images are securely uploaded and accessible across devices.
