Google added a new feature to Google Image Search with Related Queries that works for a few broad image searches like “army” and “president” but to yet, for most queries.  I read about it in Related Queries in Google Image Search , in Google Operating System.

I think related searches will be helpful for searches once it’s more available on queries that are so broad, but still might benefit (though there are political implications). 

For example, what if I typed in “artist” and Google Image Search said “try Van Gogh” – would that be saying that Google thinks Van Gogh is the most important Artist?

In this case, anything that Google rolls out, like a improvement in related search, needs to be though about first – so it doesn’t come off as too “big brother-ish”.
