Loading an image from an external source

I’m trying to load an image from an external URL into an empty movieclip on a button rollover

_root.logo.loadMovie("http://cardeldev.aumenta.net/gondolaplaza/images/logo_blackbearlodge.jpg");

Now I’ve got this working with another image I’m using but this one doesn’t seem to work. I know the image URL is correct. Any idea’s?
