Well, actually it isn't a compressed version of an image but an 
uncompressed version of an image. Maybe the naming convention is 
debatable, but e.g. k3b has the option to "burn an ISO image" (at least 
that's how I would translate the German command). The problem seems to be 
that some not so intelligent Windows programs can look inside the image 
and see the files which makes people think they could just copy the files 
to a CD. However if that program would be a bit more intelligent it would 
find out that is is in fact an ISO image and offer the option to burn it

No, nothing is extracted if you burn an iso image. The image file has the 
exact layout of the CD and nothing may be changed.

No. If you extract the files, e.g. the boot loader is missing, i.e. it 
doesn't work.

Then what would you call an "image"? IMHO, if you copy the files to a CD 
it can't be called an image because the location of the files is not 
necessarily at the appropriate position of the resulting disk. It isn't 
an image it only has a similar contents.
