Web Page thumb shots …

I have several websites, when I go to a few websites that display thumb shots of the web pages that they list, the thumb shot of that web site shows.
I made another website approx. 2 months ago and went to thumbshots.com
and registered as a free user, installed the code into my new web page.
After approx. 2 months the thumb shot for my web site is still not showing.
What is the best way to have your site thumb shot displayed?
Is there any other web site besides thumbshots.com?
Thanks
