Sometimes, when you search for images on Google, you might come across images with a web address that starts with "encrypted-tbn0.gstatic.com." These images are actually stored on Google's servers, and they help speed up the delivery of image results when you search for something on Google.

Gstatic is a genuine Google service that hosts static content on the web, such as JavaScript, images, and CSS — Google caches this static content using the gstatic domain name in order to deliver content with shorter load times.
