@Shaahin: Thanks Shaahin. I post-process in Photoshop 5 which, being ancient as myself, doesn't recognize EXIF data and dumps it when I save the file. If you can tell me how to easily append this data to a JPEG, I'll gladly include it in the future, as you aren't the first person to ask for it.

I'll e-mail you my rules of thumb.
