Dave... any burning program should be able to burn any combination of files you wish. Burning an 'image' is not relevant in what you wish. I just drag & drop the relevant files or choose them from a list.

I can't imagine why Nero would want to do only an 'image'...(does it say ISO?)

If there is some mini-version of Nero I don't know about, then just try that ImgBurn noted above.
