adding an image

Hi all!
i have a simple question that i could not find the answer to in the documentation. how do i include an image with the keypair? i had an assignment from class that says:

"Create yourself a PGP or GPG keypair with the following attributes:

  • expires March 1, 2009
  • includes your picture
  • 1048 bit minimum RSA key"

i can do everything but include and image. How can i do that? also is there a way to mass import multiple keys? i have to import 50 keys and doing them one at a time is a nightmare.

thanks for your time,
