Convert Images to one PDF

convert *.jpg -resize 50% figures.pdf;  # for *.jpg files named in alphabetical order, resize reduce the size of image
And doing the vice versa operation:

mkdir images; pdfimages -j my_pdf.pdf images/my_pdf
The command above will create the folder "images" and extract images numbered with prefix "my_pdf" into that folder.
