Do Not Show Thumbnails when I open a new tab in Google Chrome

"Taken from the Google Chrome Help Forum:

The only way I know to do this is to
go into incognito mode. To do this
hold down ctrl+shift+n and this will
open a new window in incognito mode.

If you want to run in incognito mode
all the time you can append --icognito
to your shortcut. So it would look
this:
""...\Chrome\Application\chrome.exe""
--incognito"

You can select to open your home page (which can be about:blank) when you open a new tab. Go to Tools > Options > Basic > Home Page.
