Add Spice, Goodie & Fathead example pics for READMEs

The example picture in each of the IA Repos' README's are now outdated and need to be changed so I've taken new screenshots. However, I was not able to trigger any of the Longtail IA's in the repo, at least not using the given example queries.

Do you know any Longtail queries that I can screenshot for the README?
