I've successfully tried this out in contrib/tbl/vepl2; the
vil_image_view_base_sptr arguments are all replaced with
vil_image_resource_sptr.  To be CVS committed soon.
vil_image_resource is indeed an easy-to-use interface to vil_images.
The function vil_load_image_resource() came in handy :-)

There is one slight design shortcoming: to save an image_resource to file,
one has to use
	vil_image_resource_sptr res = vil_load_image_resource("filename.png");
	vil_save(*res->get_view(), "filename.pnm", "pnm");
(note the "*" !)
Maybe vil_save should be overloaded with a vil_image_resource_sptr argument?
