How to tell google which image to pick for share with google+? -

I am working on the site z500.pl and for this:

  & lt ; Meta Property = "and: Image" content = "http://z500.pl/images/logo.gif" />

This is global but can change in every page and when I share that URL with Google, it takes an avatar to appear somewhere on the page.

Is it possible to tell Google what image to use to protect the URL? Or maybe there is a way to exclude some images.

piece. You can also use it even when you want a different image and Google+ will give it priority.
