This is called steganography. It is easy to detect if one looks for it.
Most people just look at pretty pictures and don't try to run cryptographic
software on the data bits. If one does look at the data, it is easy to
detect as an encoded message. This doesn't add any cryptographic strength
to the message, but is a form of "security by obscurity".
