Google Testing Images On Web Results Pages

Philipp over at Google Blogoscoped points out that Google is testing placing few thumbnail images from their image database at the top of web search results pages. I tried a few searches but wasn't able to see any examples. Luckily, the GB post also includes a screen capture.

Btw, embedding a few thumbnail images directly onto a page of web results is not a new idea. Ask Jeeves has done this (if the query indicates the searcher is looking for images) for almost two years. Here are a couple of examples from AJ:
