Why doesn't my likebox doesn't show any faces?

I have a likebox generated with this code:

<fb:like-box href="http://www.facebook.com/pages/Browser-Games/260061187354628" width="250" show_faces="true" stream="false" header开发者_开发百科="true"></fb:like-box>

The SDK is loaded like this:

FB.init({appId: '111929132246901', status: true, cookie: true, xfbml: true});

(website is ibrowsergame.it if you want to see the full code)

• When I'm logged in with the page's admin account, I can see the facepile being correctly filled with photos.
• If I login with another account, there are just 2 faces.

Is this just a problem of mine, or is everyone experiencing this due to privacy settings?

It's strange that there just 2 people willing to display their profile photo (out of 180). Isn't it?

The result is pretty awful, because I have around 50px of unusued white space, if no faces are displayed.

First, are you using facepile (as stated in your text) or like-box (as stated in the code example)?

If you're using the facepile plugin, this behavior is as designed . The plugin will only show the faces of friends who've liked the page/ or app. If none of your friends like it, then it will be completely blank.
