RH9 - Any idea why generating printable output from the Command Line doesn't include images?

I have a batch file that creates a printable output of our main documentation broken up into 36 separate documents, 1 per chapter. Each chapter is a separate layout. I realize that RH has its own Batch building process, but the reason for me doing it through the command line via a batch file (.bat) is that RH keeps taking focus from my mouse and it makes it difficult to do any other computer work while the RH project generates the printable output for those chapters.

Anyway, RH's Batch build works fine.

But the command line for printable output does not include any of my images in the printable output. I don't know why. The document generates with all the topics fine, but the images are missing. No placeholder box in the resulting Word doc, they just simply weren't included. Has anyone else seen this? Any way to fix it?
