If you click on the Save button, the star turns orange and the image is then saved to your "Google Save" account. If you click the 'View Saved' next to the Save button, you will access your "Google Save" items. The first time you use this service, you will be greeted with a windowing explaining the tool as follows:
"Your new home for saved images and links - Images you s ave in Google Image Search live here at google.com/save. Website links you save with the Save to Google extension for Chrome can also be found here. Tag your saved images and links to easily find them and stay organized."
To save websites to "Google Save," install the Chrome extension "Save to Google" . On the site that you would like to save, click the Save to Google extension. The extension will open a small window giving you the options to add tags. Click View Saved and your site will be saved in your Google Save.
You may be asking yourself, how is this different from the extension "Save to Drive?" Well, Save to Drive will save the site/image to your Google Drive. The site/image will become one of the many files in your Google Drive. With Google Save, you saved images/websites are stored in one central location making it easier to organize and search images and sites.
