I think that rule could use some modification; the pattern doesn't make much
sense. You probably just want ".*". Are you sure you want to redirect them
back to what I assume is your front, rather than sending them some error?

No, no conflict, but you won't need "RewriteEngine On" on both.

No need to include lower and uppercase versions of each extension in the
pattern, as you're using the NC flag. It wouldn't help much either as you
run on Windows, and thus the offenders could use URIs such as
"something.jPg" to get around it. You don't need the leading ".*" either, it
will just slow down pattern matching. Just have it as:

    RewriteRule \.(gif|jpg|mid|wav|mp3|avi|mpeg)$ - [NC,F]

You can probably put it anywhere after mod_rewrite is loaded, but I'd put it
just above the VH section. Just a matter of taste.
