system() is returning the output of the command "xxd -p image.jpg" to stdout instead of to the program.
This program relies on xxd. On machines that do not have xxd installed, this program will not work and will return an error somewhere around system().
Either there should be an appropriate error message with the directions on how to solve the problem or this reliance should be eliminated.
Currently only one level of security is available. It would be nice to have an option where instead of changing the least significant hexadecimal character but the least significant digit of the binary representation.
This would require a separate command being passed to xxd, probably "xxd -p -b image.jpeg".
