The HW3 prompt is clear about how to know when we reach the end of a secret message, but what about where the message starts?  Can we assume that the secret message will start at the beginning of the image data (the beginning of the char * array)?

Yes.  Start from the first byte in the array and continue on from there.

I guess we can start from any place of our image data ( more protective because people can't decode it unless they know where your location started) 

is the starting point for input our secret message must be the same as how we find our extra credit or we can set up any place we like?

You should make the starting location the first byte, at least for this assignment.  My decoder program can only find the message from the start of the image, so if your's isn't the same as mine, I won't able to grade your program correctly.  However if you want to write your own version (which you will not submit) then by all means create your own ^_^.
