I think the problem lies in your URL. As I understand it, the URL
"file:<filename>" will look for a file of that filename in the root
directory under Unix or c: under Windows. Try a fully qualified file name
(including the path) to see if that works. If this is an applet, create the
URL using the URL(URL, String) constructor passing the document base as the
URL argument and your file name as the String argument.
As for texLod0 not being null, it will still create the object if it
couldn't load the image specified in the constructor.
