Yes, you can add multimedia to your PAF records. The ".paf" file, however, does not store the media - only the path to it. You can read all about the procedure by clicking on HELP|INDEX and typing MULTIMEDIA in the search box and click DISPLAY. That way you will have the instructions on hand all the time. You will also be aware of just what you need to do if you ever create a GEDCOM of your ".paf" file, that contains "media", to send to someone else.
