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.
