In its efforts to compete with Bing, it looks like Google has rolled out larger pictures for female celebrities. After a couple of searches over the past week I though I saw a trend, but to confirm it I Googled the names of the winner of the best actor/best actress from the last five years and sure enough found Google was doing this.
For easy reference I have included the links below:
Female Actors
Reese Witherspoon
Helen Mirren
Marion Cotillard
Kate Winslet
Male Actors
Philip Seymour Hoffman
Forest Whitaker
Daniel Day-Lewis
Sean Penn
