    so in one of my assembly language classes we did this program that took image files (.jpg) and decrypted hidden messages that were placed in the least significant bits of the file.

    what i want to know is how do you put messages IN these bits? in essence reverse the program that we did. does anyone know how to do this??

    Since you wrote a program that reads a jpg file, you should already be familiar with the jpg file format. You could simply write a program that reads a jpg file, modifies the appropriate bits, then writes the modified data to a new jpg file.
