This image viewer offers built-in e-mail, FTP support and compression functions. You can select a group of images and e-mail them, upload them or create a ZIP file. You can also browse images by folder, find images on your computer and make HTML thumbnail pages. Also included is an image slicer that can "chop up" a large image into smaller ones, then create the correct HTML code to put it all back together.
