Hello,
I agree with you that such differences are, as you said, "very apt" to
go unnoticed, although I suspect there are some who would notice. I am
reluctant to use absolutes in cyber conversations, as they are
frequently considered provocative.

Human imagination can be wanton. If you present a more or less random
pattern, such as an ink blot, to the average person, he is likely to
discover many things within the meaningless form -- but such things
will have no basis in reality. That's why we always need an objective
measure.

Cyber conversations can be problematic for the same reason. If one
seeks provocation, perhaps only unconsciously, then one will tend to
discover provocation whether it exists or not.

Science is more than a white coat and a job in a laboratory. Science
is the ability to discover what really exists despite the trickery
of imagination.

The above link, when you view it, does it look identical to the image
below.
reason why I ask is on my monitor, the link above is obviously
compressed but the image below
is the same image, just not uploaded onto my website. The image i post
below, looks good and the compression is nowhere near as evident.

Yet it is the same image.
Is this glaringly obvious to you guys as well.

Gday Glenn,

The missing bytes are the EXIF data. Any differences in compression
would be noticeable by the artifacts around any high-contrast edges (for
example, the aircraft in flight).

Regards, and thanks for wonderful images,
Pat

Exact, there no EXIF data and no ICC profil in the picture from the web.
You can see the differences when you open the two files in the same
progam. (preview in macos X 10.4 in my example)
The newsgroup file is daker and you can see less artifacts than the web one.
