There are a few things you could do to get the search results you want, things which Google doesn’t openly talk about.
Search pictures by region –
In case you want to view pictures from a particular region or country all you need to do is go to the Advanced Search page and select the region form the drop down menu. You can even define the file type: jpg or gif or png etc.
Search for people’s profiles –
if you want to search for people’s profiles, without having to go to Google Plus every time, then doing this is possible. Simply open Google.com in a new tab, do a name search and then add “&tbs=prfl:e” to the search URL. This limits the search results to only people’s profiles.
Read articles without paying –
According to Business Insider you can also use Google for read articles from websites like the New York Times that keep information behind a pay wall. You have to search for the article by its exact title on Google and it would be displayed in search results.
Lock Google’s Safe Search –
You may have enabled the Safe Search option from Google’s search settings to keep explicit content from being displyed up in results. If you want to ‘lock safe search’ to keep others from changing it on your computer, then you can do it from the settings page. Once you have locked the Safe Search, coloured balls would appear in the search results page signaling that results do not include explicit content.

Also, there’s a lot of hidden features in Google.
