   Even better, you can right click an ISO and it will mount it also as a virtual   
   CD/DVD.   
      
   "The .img filename extension is used by disk image files, which contain raw   
   dumps of a magnetic disk or of an optical disc. Since a raw image consists of   
   a sector-by-sector binary copy of the source medium, the actual format of the   
   file contents will    
   depend on the file system of the disk from which the image was created (such   
   as a version of FAT). Raw disk images of optical media (such as CDs and DVDs)   
   contain a raw image of all the tracks in a disc (which can include audio, data   
   and video tracks).    
   In the case of CD-ROMs and DVDs, these images usually include not only the   
   data from each sector, but the control headers and error correction fields for   
   each sector as well.   
      
   Since IMG files hold no additional data beyond the disk contents, these files   
   can only be automatically handled by programs that can detect their file   
   systems. For instance, a typical raw disk image of a floppy disk begins with a   
   FAT boot sector, which    
   can be used to identify its file system. Disc images of optical media are   
   usually accompanied by a descriptor file which describes the layout of the   
   disc, and includes information such as track limits which are not stored in   
   the raw image file."
