Cannot load images from URL, but ok from file?

Question

Hi people,
In the followint simple code (I'm eventually placing these into a media tracker), when I'm debugging on my local PC, the images load no problem, but when I deploy to the web they do not. The rest of the application carries on regardless however. I'm wondering if this is a sufficiently generic method of getting media resources. http://www.thermoteknix.com/93266898/VirtualVisIR_Main.htm (its a simulation of one of our new infrared cameras). I cannot get it to load media, unless its from my hard-drive of course!
Does anyone know what I should do instead?
URL Url = Parent.getDocumentBase ();
VisIRBackground     = Parent.getImage ( Base, "images/rear view.jpg" );
VisIRThermoIcon     = Parent.getImage ( Base, "images/redonion.gif" );
VisIRIndigoIcon     = Parent.getImage ( Base, "images/indigo.gif" );

Ok, just in case is isn't anything to do with paths, here is my loop to load all of my images (which have been created with getImage (x,y)):
Is this technically correct? I've added the images to the media tracker with an incrementing ID, so we have 1 ID per item, starting at zero.
for ( nImagesLoaded = 0; nImagesLoaded < nImagesToLoad; nImagesLoaded++ )
     try {
          VisIRMediaTracker.waitForID ( nImagesLoaded );
          bFailed = VisIRMediaTracker.isErrorID ( nImagesLoaded );
          if ( bFailed )
               break;
     catch ( InterruptedException e ) {
          System.err.println( e.toString () + new Integer ( nImagesLoaded ).toString () );
}
