Answer 1

Since, its existing pdf, the most easy way to do it is:

1. Convert pdf to .doc or .odt ( Check http://www.zamzar.com/ )
2. Add images into the converted file however you want.
3. Convert back to PDF (openoffice and libreoffice makes it easy to save pdfs)

PS: If the pdf file needs to further edited always keep a backup of source .doc file, so that the changes can be done easily, too much conversion have bad effects on file quality.
