Urgent SmoothGallery Problem – Please Help

If you look on my site, http://www.crystalgamer.com you will see that I have a smoothgallery slideshow on the homepage.

You will notice that it has turned white and the images seem to have disappeared. I do not know why this has happened as it was working fine earlier.

I have got the correct values in the custom fields for all the posts but I am not sure why the images are’nt showing.

Please can someone tell me how to fix this problem and get the images back on.

Many thanks
