Just highlight what you want (including images), right-click it and select Note This. It will then be transferred to your notebook alongside the rest of your clippings.
You can also use it to store ideas, thoughts, notes, and bookmarks. Google Notebook now supports labels, making it a powerful organizer for all your information.
How do you get started? Simple. Just sign in to the Google Notebook homepage with your Google Accounts username and password, then download the Google Notebook browser extension (if you haven’t already). As soon as you restart your browser, you’ll see a Google Notebook icon in the bottom-right corner of your browser window. Click on this icon to open your mini Google Notebook, where you can save all the clips of content you want.
The mini Google Notebook allows you to clip information from the web without ever leaving the page you’re on. You’ll never again need to toggle between windows, or copy and paste info from your browser window to another application.
