lsb universal decoding

[royfrancis]

The decoding using this package return sthe encoded information. It works. I was curious if the embedded information could be retrieved by other lsb decoders. I tried a few online and it didn't return the embedded info. So, I was wondering if this encoding is a standard or the implementation varies from tool to tool making them cross-incompatible?

oh dear - the implementation here was done after a conversation in a pub and a quick look on wikipedia, so it's quite likely that it's not standard...
