I figured out how to do this using the FreeImagePy libary.
import FreeImagePy as FIPY
F = FIPY.Image()
F.new(multiBitmap = "multipage.tiff")
F.appendPage("test1.jpg")
F.appendPage("test2.jpg")
F.deletePage(0)
F.close()
The output file is a multipage tiff file.
EDIT: I am having a problem with unusually large file sizes. Does anyone know how to compress the resulting multipage tiff file when the file is being generated?
