The results were surprising, and quite conclusive. Consistency of

the big deal about embedding them. If they're truly ignored by all
but the very few applications, why not? It doesn't hurt anything and
even at 28.8Kbps dialup speeds would only add 2-3 seconds per image
to download. Crap that isn't color management sensitive, like all the
stupid dancing whirlygigs and other nonsense that people embellish
their sites with, don't have to worry about it. (I often turn the
browser display of graphics off when I see that crap anyway.)
Enhanced? It either works or it doesn't work. It's as easy to prove
whether it
does on not by simply displaying an Adobe RGB formatted and ICC
embedded image
on any windows browser. Inevitably the image will be rendered
obviously non-
colour managed.
Perhaps you don't understand. The images were set to be in sRGB
colorspace. Each image was saved with and without an sRGB ICC embedded.
I said, again, 'the consistency of the rendering was enhanced when an
ICC profile was embedded'. On both platforms (Mac OS X and Windows
XP), in 8 different browsers we saw the same things. It was
measurable. That's what we were looking to test for, to see if there
was an observable difference in the consistency of rendering, not
whether the browsers would read alternative colorspace profiles.
Send me the images that you and your associate tested to derive
your results
and I'll use my screen colorimeter to test them and report back.
Sorry, the tests were done three years ago ... I'm pretty sure I
still have the files and data somewhere, but a quick search hasn't
brought them up. They're probably in one of my system archives as
they weren't a part of my regular photo work, just some testing for
web display.
