Random idea -> Data to Images

[JmZ]

Well this is fairly easy to make. However, doing it in a FPL is another ball game if you're used to 'simple' imperative programming like me (like c, php, java, ...)

Some of them use AES, triple-DES, blowfish, etc. to encrypt the hidden file also. So it isn't so easy to make once you start looking into encryption techniques.

A lot of the apps available just stick it on the end of the image file. But better ones encrypt the file, shuffle the data around and such.
