One thing I'd recommend is doing something to trap missing images - missing images toss 404 errors too, just not visible to the user. So you can test for file extensions in the code, and if it's GIF or JPG or PNG or whatever, you can use CFCONTENT to replace the image with a clear gif.
I do a custom 404 template that tries to find a .htm, .html and .cfm page that matches the user request, then tests for image extensions, then puts the error in a database. Then each night at midnight I've got a scheduled task that runs, grabs the errors, puts them into an email and sends me my daily 404 Digest to pass out to developers to fix, trap or whatever. It's really helped cut down on the number of missing links and images people get from our applications. We do the same thing with application errors - except those aren't digested, they're instantly emailed to us and shoved into our project manager so that we can catch errors as they arise and stay on top of things. We then use the database of errors to track bug history and template information. We can dump out a report on say Index.cfm that shows all errors that have occurred in the template over time, as well as any errors in included templates or tags that are called from Index.cfm Those global templates are pretty powerful if you make use of them.
