A thumbshot
We use Thumbshots to generate the thumbnail sized image of client Websites. In some cases when a site is new Thumbshots doesn’t have an image stored in it’s database. Usually this is only a temporary situation that rectifies itself as it’s search engine spiders see our request to grab an image of the site. More information on this can be found here:
If they have an image of a site that is out of date it can be update here: Update Thumbshot Image
