FTP (File-Transfer-Protocol) is an easy to use method for exchanging digital files on-line. It is generally far more reliable than e-mailing an individual file or group of images and is essential for sending large files such as TIF, PSD or RAW. Windows XP users can utilize Internet explorer in the FTP Browser mode which is explained below, or you can employ a stand alone FTP program. MAC users can get applications such as FETCH, FILEZILLA, CYBERDUCK and others to access our server and upload files.
