What are image2, image1? Are they arrays? Paths? What format are the images? What do i,j, and k represent? You need to more clearly define the problem and show what you've already done. There are libraries available that support different formats, but you should be specific about what you need.

1) You have to get the format of the pixel, in that type of picture - and there are many types of greyscale. You can google the format.
2) Make the number of variables (and type - probably unsigned char, but it could be int), you need, to correspond to your pixel's format.
3) write out the new data with the changes you made. Don't try to actually alter the file, in place.
