The files are no longer accessible under the URLs you posted. But I
assume what you have here is a transparent image in which case two
/Image objects are produced: one for the image data and one for the soft
mask (alpha channel). If one of the image object has a "SMask" entry,
it's that case and that Image object would be the main one.
