Google is no longer following the "do no evil" software development model.

You’re Not Just The Product, You’re The Ads (And Your Friends Should Thank*You)

Today, Google announced “Shared Endorsements”,
an expansion of its program of using your Google+ ‘+1s’ in ads.

Now Google can show your activity such as following a brand,
commenting on a post, or reviewing a business in ads
that feature your name and face to people you allow to see the actions you took.

Google lets businesses pay it to share those endorsements with more of your friends
than would have seem them normally in search results, maps, Google+,
and elsewhere. And Google’s not alone.<snip>

If it's your image, you should be able to copyright it and at least get royalties from it's use.

How long will it be until some eager lawyer starts suing Google
for using your image without permission in it's new business model.
