Hi!

I suppose the GIF to be b/w (use any image handling program to achieve this)
Use giftopnm to convert it to a portable bitmap and then pbmtoascii to convert
that format to ASCII. Some excerpt from the pbmtoascii man page will help you
when using nont b/w pictures. Note that the tools mentioned are command line-
based so they should work under any OS at hand (even Windows Monday Edition).

NAME
       pbmtoascii - convert a portable bitmap into ASCII graphics

SYNOPSIS
       pbmtoascii [-1x2|-2x4] [pbmfile]

DESCRIPTION
       Reads a portable bitmap as  input.   Produces  a  somewhat
       crude ASCII graphic as output.

       Note  that  there is no asciitopbm tool - this transforma�
       tion is one-way.

OPTIONS
       The -1x2 and -2x4 flags give you two  alternate  ways  for
       the  bits  to  get  mapped  to  characters.  With 1x2, the
       default, each character represents a group of 1 bit across
       by  2  bits  down.  With -2x4, each character represents 2
       bits across by 4 bits down.  With the 1x2 mode you can see
       the  individual  bits, so it's useful for previewing small
       bitmaps on a non-graphics terminal.  The 2x4 mode lets you
       display  larger  bitmaps  on a standard 80-column display,
       but it obscures bit-level details.  2x4 mode is also  good
       for displaying graymaps - "pnmscale -width 158 | pgmnorm |
       pgmtopbm -thresh" should give good results.
