This came up at a WEB site development class I took 2 years ago
sponsored by the American Graphics Institute. The instructor
explained that if <Save> is used instead of <Save As...> there would
be no further degradation of the image with multiple saves.
How could this be?! I thought this was strange. This sounds to me
like parts of the image that are unmodified use existing compression
and only new pixels are run through the compression mashing of jpeg.
I never tested this because this class is what woke me up to the fact
that I don't like this
www-HTML-image-slicing-mapping-jpeg-gif-low-image-resolution stuff
and I should stay with my background in print.
I am curious to know if anyone else has heard of or tested this.
