Thanks Yehuda,
I tried your suggested code already and have just retried it. The behavior is that all jpg's are now not showing at all.
>From what I tell from the rewrite.log, it is pasting the DocumentRoot path in front of the path to the "no_sketch.jpg" for all JPG references.
The DocumentRoot is "/mnt/data/pawebdata/docs"
Here's what the log shows is being used for the path to "no_sketch.jpg"
/mnt/data/pawebdata/docs/images/sketches/no_sketch.jpg
Note that I did not configure this Apache environment. I'm coming in (inexperienced...but not dumb) with the assignment to show "no_sketch.jpg" for missing JPGs in the /image/sketches path and having to work with someone else's configuration.
So I'll try to give the best information I can.

You need to use RewriteRule, Redirect has nothing to do with RewriteCond.
Something like the following should be enough:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(gif|jpe?g|png|bmp)$ /images/sketches/no_sketch.jpg [NC,L]
I also usually recommend not using the <IfModule> directive. If you want
this to work, you probably want the server to show an error if the rewrite
module isn't loaded rather than ignore the configuration.
