PicXchange - Version 1.0c Share and exchange directories of images and graphics with friends. PicXchange dynamically scans directories that you authorize and generates thumbnails on the fly; when a thumbnail is selected, a picture is sent. PicXchange uses compression and encryption for fast, secure transfers. Integrated chat lets you talk confidentially with friends. Because of its mesh architecture, picXchange also allows multiple users to access a collection simultaneous (creating a dynamic chatroom on-the-fly.)
