I put the "no_sketch.jpg" image in path "/mnt/data/pawebdata/docs/images/sketches" and indeed, every jpg showed the "no_sketch.jpg" image.
The 302 didn't seem to do anything.

Yes there is an alias for the images specified in the vhosts.conf file. :)
Alias /images/ /mnt/data/pawebdata/images/
<Directory /mnt/data/pawebdata/images>
AllowOverride None
Order allow,deny
Allow from all
</Directory>
I can create the directory path "/mnt/data/pawebdata/docs/images/sketches" just to see if the "no_sketch.jpg" shows. But that couldn't be the permanent solution.
I will also try the 302 thing.

The images have to be accessible somehow: Just to clarify, you said:
- The DocumentRoot is "/mnt/data/pawebdata/docs"
- The images are located in "/mnt/data/pawebdata/images"
How does the browser ever load any image? Is there an alias directive
somewhere in the configuration?
Can you put the image at
/mnt/data/pawebdata/docs/images/sketches/no_sketch.jpg and see if it works?
You could try an external redirect instead, but I haven't tested that
myself.
I recommend making it a temporary redirect (302) rather than permanent
(301):
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(gif|jpe?g|png|bmp)$ /images/sketches/no_sketch.jpg
[NC,L,R=302]
