When you search for something using the Google Chrome address bar – known officially as the "omnibox" – the search suggestions create image previews. This can be unnecessary (or even annoying) in many situations. To disable these previews:
Disable Rich Entity flag
To disable the feature, you must disable a Chrome flag. These are hidden settings that are not yet suitable for the mainstream, but still offer powerful optimizations for your browser. It's worth noting that Google is constantly tweaking and modifying the flags so they can disappear or stop working at any point – just a few steps before we get started.
First, open a new Chrome browser tab (or a new Chrome window)). Copy the following line, paste it into the Chrome address bar (omnibox) and press Enter:
chrome: // flags / # Omnibox rich entity suggestions
 This will take you directly to the right marker.
Click on the drop down box and set it to "Disabled". Then start your browser with the bottom of neu the bottom.
Again, Google may terminate (or move the settings) menu as an official feature at any given time. but until then you can do a cleaner search in the search bar.
This marker was used as of Chrome 75 in May 2019. This is the Chrome version that added the pictures. 
Alternatively, you can completely change search engines (on DuckDuckGo or Bing) or browsers if you like the approach "Let's burn everything down". We hear that Firefox is great now.  on Ghacks
