Facebook share not recognizing image thumbnail

Facebook share not recognizing image thumbnail

I have created an facebook share button using the url below:
http://www.facebook.com/sharer/sharer.php?s=100&p[url]=http://www.elementalworks.nl/KPJH/Homepage&p[images][0]=http://www.elementalworks.nl/KPJH/images/logo.jpg&p[title]=KPJ
Halsteren voor jouw schuurfeesten en trekkertrek
activiteiten&p[summary]=Schuurfeesten, Trekkertrek en allerlei andere
gezellige bijeenkomsten vindje bij KPJ Halsteren
In addition to this i placed the open graph image tag as follows:
<meta property="og:image"
content="http://www.elementalworks.nl/KPJH/images/logo.jpg" />
BUT.. the facebook debugger (https://developers.facebook.com/tools/debug)
sais that the image is'nt big enough, it has to be 200x200. The image
itself is 365x250 50kb.
Strange thing is that in the small preview window below the debugger the
image does show.
So why doesnt it show at the moment of sharing? You cna find the page in
question here: www.elementalworks.nl/KPJH
