Google-chrome – How does Chrome choose the thumbnail for frequently visited websites

google-chrome

One of the options in Chrome is to have it show the most visited pages when you open a new tab. It also takes a snapshot that is displayed as a thumbnail for each site, e.g.:

enter image description here

How is that snapshot chosen? Are they just taken at set intervals? Is there a way to force another one to be taken?

Best Answer

The thumbnails you're looking for are stored in a cache in the Chrome User Data folder, which is located at

%LOCALAPPDATA%\Google\Chrome\User Data\Default\                       (Windows)
/users/[username]/library/application support/google/chrome/default   (OSX)
/home/<user>/.config/google-chrome/default                            (Ubuntu)

Just delete the Thumbnails file. Once that's done, revisit each site you care about to make Chrome generate a new thumbnail for that site.
