I'm trying to figure out how to use Google Authorship with my WordPress blog. I have a Google+ account from which I have done a custom link to my About page with a refer back to the Google+ account from the About page. I'm not sure what esle I'm supposed to be doing to to enable Google Authorship. I know this isn't an entirely WordPress question, but I really want to add that little picture to my search results. Does anyone have any tricks or tips on how to do this? Do I need to be Pro and have a plug-in to do it, or can I do it with my free WordPress account?
The blog I need help with is iosaffairs.com.
