Just use pdfimages:
Change yourpdf.pdf to the name of your pdf
output-name is the name format (eg. output-name01.jpg output-name02.jpg) is how the files will be named if you use "output-name". Change as needed.
pdfimages -all yourpdf.pdf output-name
After that you will have extracted all of the images.
You can also just run the command with -list and see all of the images contained within the pdf like this:
pdfimages -list file.pdf
page num type width height color comp bpc enc interp object ID x-ppi y-ppi size ratio
