yes, that's the question to ask, i think
but we can complicate it, to make it more easy: on linux, download imagemagick and in a terminal enter:
Code: Select all
convert picturenames_*.jpg outputpdfname.pdf
the results were sometimes huge in size, you had to wait for several minutes or tweak parameters until...
that was some years ago - it stopped working (because of softwareupdates, i think).
