Sorry for not being more clear here, and it was not really a question, I
basically wanted to check if there were any major objections to it.
For cases when you have the image lying in a web-accessible directory (could
also be on another server), or when any dynamically created image (graphing
tool, ArcIMS/mapserver, captcha etc) are dropped in a web-accessible directory,
you should do a cflocation rather than a cfcontent output.
That way you can do whatever processing you want before, and hand over the work
to the web-server (doing what it does best - serving static content), instead
of occupying a thread in cfmx with just outputting something. Not so important
for small images, but anyways.
Web browsers don't seem to have any problem at all with that (from just a quick
test) -- they happily go through the request and receives the 302 header to the
new location, and load+display the image.
Another thing: This way you don't have to worry about setting the proper mime
type headers, the web server should do that automatically.

Hugo... ummm...
CFLOCATION to where? CFLOCATION does a client-side redirect via headers
(similar to a meta redirect).
CFCONTENT sets the mime type of the content stream that gets returned
to the
browser (hence making a CFM template look like a JPG or a PDF).
Perhaps I'm missing something obvious, but I don't see how their
functionality could be analagous.
Maybe a bit more explanation?
