I know very little about #pack, so I can't help you there. However, I
can offer a slightly more terse (faster?) way to get the same array of
strings:

  # Treat strings as one byte per char ascii
  $KCODE='a'
  File.open( "test.JPG", "rb" ) do |image|
    @image_array = image.read.split('').map{ |ch| ch[0].to_s }
  end
