    First step perhaps would be to find out all the info you could on the JPEG format. Perhaps checking out the information available from wotsit.org would help. Once you have figured out how the information is stored within the JPEG format, you will have a starting point for your program to then modify the data.

    working with the .jpg format is a biatch in c++ but it has been made considerably easier now since the advent of GDI+. Look up GDI+ at msdn and review the sample source available.
