Nobody need put words in those pictures. It is called lossy compression. A picture can easily be changed (byte by byte) and you would never know the difference. Even undecipherable color pixel changes, that nobody would notice, can be secret messages or computer code to compromise your data. Pictures (ie lossy compression) can easily compromise computer security.
