JPHS (JPHide, JPSeek, JPHSWin, JPHideandSeek) by Allan Latham is a steganography program that hides information in JPEG files with password protection.
Source code and versions for DOS, Windows and Linux are available.
The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. Above 15% the effects begin to become visible to the naked eye. Of course some images are much better than others when used a host file - plenty of fine detail is good. A cloudless blue sky over a snow covered ski paradise is bad. A waterfall in a forest is probably ideal.
There are reports that the original one crashed all the time. If that happens to you, try the version from SSAK or Steganography Toolkit.
