Concatinating PDF files

[sophie_newbie]

I am converting TIFF images of patents to PDF files. Each patent comes
in about 20 seperate TIFF images and I want to put them all in the one
PDF file. Is there a way to do this? Using the Image library I think
you can only convert individual TIFF images to PDF?

Maybe there is a way of concatinating these files or maybe there is a
way to create the PDF from the TIFFs in the first place?
