PhotoViz is a program to view secret messages, contents and applications hidden in images. All images can be viewed by any available image viewer software but nobody knows that the image contains hidden content. They looked just like any other images and with no loss in image quality. PhotoViz provides security and secrecy by ensuring that only the targeted audience can retrieve the contents in the image. PhotoViz can also automatically enhance and fix basic problems in digital photos. It is designed for casual photographers and business users who want to improve their photos for prints, emails, presentations and sharing on the Web.
