how to edit a nero cd image and not change size?
 

I have been trying to add/delete files to a cd image editing and saving the image changes size from 700mg to over 1.6 gig. Is there a utility that does notchange size for imag or will burn a 1.6g image to disk? I am using nero 5.9 I have tried several iso editors all change size of copy, Is there a way to compess the image size?
