If you're reading this on ftp.slackware.com, you will find that the ISO images are not here. This is because we simply don't have the bandwidth at ftp.slackware.com to provide ISO images. ISO downloads take a long time, and block people from retrieving small updates. If you're looking to download the ISO, consider using BitTorrent. If there are active torrents available, information may be found on on http://slackware.com. BitTorrent is available as a package for Slackware in the /extra directory. Mirror sites may also have the ISO images up for FTP. Use the .asc files here to verify your ISO images are authentic.
