Yes, I was hoping for a way to do exactly that without influencing the image 
data. Latex is one possibility but I would prefer to not have to write the 
script myself :-) I want to do something like:

$ jpg2pdf *.jpg doc.pdf

for an arbitrary number of JPG files of course

Maybe I will write a latex file that contains some fancy looping over all JPG 
files in the current directory, or a shell script that generates a taylored 
latex file and thereafter compiles it to PDF.
