This seems to be a bug but could be a test where Google is displaying a large box of image results for queries by the searchers. This is not something new, but to display a lot of images for so many variations of the queries is not normal. So, this is potentially a Bug.

Google is now showing Image packs on all keywords, also on terms where it's not necessary at all! ?
So is it permanent now or just a bug? ?@rustybrick @methode @sengineland @sejournal @sewatch pic.twitter.com/jLQZOCCN2A
