 		FOLLOWUP
I found this gem at:
http://httpd.apache.org/docs-2.0/env.html#examples

SetEnvIf Request_URI \.gif image-request
SetEnvIf Request_URI \.jpg image-request
SetEnvIf Request_URI \.png image-request
CustomLog /var/log/httpd-access.log combined env=!image-request

Restarted httpd and no more images (of the kind described above anyway) 
were logged.

Still outstanding is the other task of conditionally logging attempted 
exploits, (but not the output)  and confirming URL-rewriting is working 
as per my other post this morning.

Regards to all,
-Colin
