Partly depends on what you want the UNIX machine to do with it. If you
want it webworthy, convert it to .gif or .jpg - UNIX can do this, or you
can (much easier and much, much more fun) use Paint Shop Pro, which you
can download free for awhile - but it's worth paying for. Any number of
graphics programs nowadays convert nicely. And the UNIX machine can read
your DOS disk & files. Depends what you want to do with it.
