Yes, it is possible to save the entire contents to an external source, however the odds of being able to save an entire disc image to a CD-ROM is quite low. What you would need is either A) an external HDD or B) a DVD burner and DVD's assuming that your image is under 4.7 gigs. An image is an exact replica of your HDD, yes you can choose what you put on the image, but as far as content loaded it loads all of what the image contains if used the way the image is intended which is to restore the computer to the day it was imaged (however, you can load individual content by exploring the disc)
