I've had to do this with directories full of TIFFs a few times over the
years and finally wrote a script. I found that working with ImageMagick
alone really taxed the machine (may it's pulling all of the images into
memory or something?) and so it was more efficient to make a PDF of each
page and then use pdftk to string the PDFs together at the end.
I'm not saying I'm proud of this, but it works, and could easily be
modified to work with JPEGs.
