Timthumb not working with Facebook images

Hey guys you’ve been life-savers so far. Thanks a ton for that. I need one last help. My website uses timthumb.php to resize images. It works fine when I add jpeg links from flickr.com. But when I add photos from facebook they dont show up with timthumb.

I added their link facebook.com and sphotos.ak.fbcdn.net(this the link when you open images in facebook) to the allowedsites section but it doesnt work. Can somebody help me out ?

The link to the website is : http://vigaversa.co.cc

Thanks 🙂
