The example was not presented as one for "practical use", it was merely a
functional example.  It's purpose is to show that all images could be
treated through a simple procedure.  Tim said that it was nearly impossible.
The example was to show that it is not nearly impossible, in fact, that it
is easy.

The question, as I interpreted it, was that HTML could not zoom it/out on
images.  I'm not splitting the hair, I'm putting focus on the hair that was
originally presented.

The question was, "Can HTML zoom in and out on images?"  I'm not arguing
quality of images.  The statement was that he (Mike) could not imagine HTML
scaling images.  I merely answered and showed an example that it could.  The
hair was split by expanding the focus to "hundreds of images", image
quality, and plots.  I'm answering one question, "can HTML scale images?"
The answer is yes.

I don't think so.  However, since the point was brought out earlier that PDF
viewers are redistributable, it should be noted that IE is redistributable.

If I were a betting man, I would bet that I ruffled feathers by using a
VBScript example.  The anti-Microsoft sentiment is too hard for some to
stifle.
