I wrote ImageIntrinsics, the class that supports the simg: functions
without a lot of care. It basically ignores errors, which is bad.
I've just added two error messages to the class. It will now print

  System.err.println("Failed to interpret image: " + imageFn);

if it can open the image file but can't interpret it. 

It will print

  System.err.println("Failed to load image: " + imageFn);

if it can't open the image.

Maybe that will help.

                                        Be seeing you,
                                          norm
