and here is how you do it in nero:
The Nero H4elp files should also have an answer for you.
I have an .img file that is 752MB but I only have a 700MB CD/R disk. I tried burning it to a DVD+R disk but it gave me errors and had to throw the disk away. I have Nero 7 Ultra Edition. Is there anything I can do to burn this .img file onto either the 700MB CD/R by some method (compression or whatever, not sure if this is even possible but worth an ask) or onto the DVD+R disk? I'm guessing I couldn't burn it to the DVD b/c of a format issue. Thnaks.
