The Google Drive team released a new Chrome extension called "Save to Google Drive," that will allow you to save documents, images, hyperlinks and other media directly to your Google Drive. You don't have to install Google Drive for Windows.
After you save using the extension, you'll see options to immediately open the file in Drive, rename it, or view it in your Drive list, where you can do things like add it to a folder or share it with others.
