The "8" argument here is totally bogus, it will only work if your
display is 8-bit. If window->window existed (and it doesn't here) 
you could then pass -1 for the depth to use the one from the window.
However in this case you might do:
 gdk_pixmap_new (NULL, 262, 392, 
                 gtk_widget_get_visual (window)->depth);

You need to look at the "scribble" example in the GTK tutorial for how
to go about displaying the pixbuf. The tutorial is on www.gtk.org.

These are from the depth of 8.

In GTK 2, you could just do:
 image = gtk_image_new_from_file ("test.jpg");
 gtk_container_add (GTK_CONTAINER (window), image);

So look forward to that. ;-)
