I'm using the Rich Snippets with two of my websites: http://www.meow.fr and another one.
They both have the same two authors: Jordy and Jing. What is amazing is that the Google+ profile picture is shown for Jing but not for Jordy (which is me). I have NO CLUE why, it's beyond my understanding. And Jing is lucky because she didn't set a thing ;)
Please check this Google result:
Check the first page, the second, the third... basically, she has a badge for all her articles, but there are none for mine.
I have no idea what to check, everything seems to be in order. There could be something wrong with my Google+ account but what? I don't know. Google is full of mysteries.
Of course I tried the Rich Snippets Tool which works perfectly for every pages.
