I could add it.  You could easily do the following to exclude images:

<MIMEFilters>
image/*;	m2h_null::filter;	mhnull.pl
</MIMEFilters>

To allow exclusion based on filename, I could add exclusion by filename
extension.  This will avoid the overhead of regex re-evaluation each
time the filter is called.  The only time filename exclusion really
has applicability is when data is specified as application/octet-stream
and the filename parameter is the only clue on what the content-type
may really be.  Of course, you could always exclude all data specified
as application/octet-stream as described above.

A somewhat-related change is to support exclusion based on data
size.  I.e.  And data over a specified number of bytes will not
be saved.

This should be easy to add.  BTW, what do you do about the index
pages?  I.e.  The message will still be "removed" wrt index page
generation, so the only way to get to the files would be from
search results.
