Tumbnail Image viewer - Goblins?

[clangsdale]

I installed the Thumbnail Image viewer script. It looks great! It worked great and then all of a sudden on popup there is a white screen over the images??? It works fine on my HD but on the server it isn't. Goblins maybe? Any suggestions?

Thanks guys
