Thank you for your fast reply. I would just like to make sure I was well understood, though. The result I want is not a multiple page JPG, but a single JPG, akin to what I would get using the web utility FileMerge.
The reason I installed (and discovered) PDFCreator is that to translate Word and other documents to jpg, and fuse them together in a single file, I used web utilities like the one I just mentioned. But, I’m uncomfortable about doing it this way (security).
