Of course they are bigger than text

Right, and that is the issue. In a text newsgroup, things are optimized
for text. Anything that is not "text sized" gets in the way, whether on
the server, in the software required to view, or in the time people have
to wait for the unwanted image to be presented to them. "Things that
don't fit" should be segregated. This includes binaries (post to a
binaries group). It also includes topic drift (change the subject, use
prefixes) and HTML (put that anywhere else but Usenet).

Doing this makes the experience better for all.
