Enable image search
If the sites in your custom search engine include images, you can enable image search. Your search engine will display image results in a separate tab from web results.
Things to note:
- Custom image will vary from those returned by Google Images, even if you’ve configured your search engine to search the entire web. That's because Custom Search is designed to present a more personalized experience.
- Some features, such as Autocompletions and Promotions, aren't available for custom image search.
