FB Like in thumbnail problem

Pozdravljeni,

zanima me če mi kdo lahko pojasni sledeče:

Imam stran : http://travelscams.net/like-tes/ kjer testiram "Več lajkov na isti strani".

Zanima me zakaj ko nekdo LIKE-a mu na facebook sicer napiše da je lajkal in pri tem da pravilen LINK, vendar thumb ni NOBENA od teh slik, ampak random slika ki je tudi na site-u. Any ideas?

Koda izgleda nekako takole:

<div id="fb-root">

<a href="http://travelscams.net/wp-content/uploads/2012/05/mexico-souvenir-shop-scam.jpg"><img class="alignnone size-thumbnail wp-image-82" title="mexico souvenir shop scam" src="http://travelscams.net/wp-content/uploads/2012/05/mexico-souvenir-shop-scam-150x150.jpg" alt="" width="150" height="150" /></a><fb:like href="http://travelscams.net/mexico-the-non-profit-souvenir-shop-scam/" send="false" layout="button_count" show_faces="false">/fb:like

<a href="http://travelscams.net/wp-content/uploads/2012/05/New-york-city-CD-scam.jpg"><img class="alignnone size-thumbnail wp-image-76" title="New york city CD scam" src="http://travelscams.net/wp-content/uploads/2012/05/New-york-city-CD-scam-150x150.jpg" alt="" width="150" height="150" /></a><fb:like href="http://travelscams.net/usa-new-york-city-cd-scam/" send="false" layout="button_count" show_faces="false">/fb:like

<script type="text/javascript">

2 window.fbAsyncInit = function() {

3 FB.init({appId: 'put your fb app id here', status: true, cookie: true, xfbml: true});

4 };

5 (function() {

6 var e = document.createElement('script'); e.async = true;

7 e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';

8 document.getElementById('fb-root').appendChild(e);

9 }());

10 </script>

</div>

Ali je mozno da obstaja kak "default" thumbnail, kajti tudi če grem na katerikoli post in dam like, mi vrze isti thumb (telefonček) ven... Any ideaS?
