My father gets all of his pictures developed on to Kodak CDs. The quality is exceptional, the photos are beautiful and the files are HUGE.
He's looking for a way to convert those files into smaller files so that they'll be easier to email. He doesn't want to zip or compress them, he just wants to convert them to a file that takes up less space. I realize that with space goes quality, but these pics will be viewed primarily on a monitor anyway, so they don't need to be of the higest quality, they just need to give the relatives on the other side of the country a good idea of how the grandkids are lookin' these days.
