how2 edit an cd image

[pr0iv2]

say you copy a cd that has some sort of protection on it
and make an image onto your harddrive

if you wanted to add a file to the image how would you do so?
without screwing up the image?

winiso doesnt work very well when i try this.
any other program work with editing images?

winiso is the best for doing this. ultraiso maybe?
