Strange problem and strange solution with disc image

I was a bit shocked when I loaded up a Adobe Illustrator CS2 image in Alcohol 120% and found that even though the image was loaded, Alcohol 120% couldn't recognize the disc! After being panic for about 3 seconds, I figure out a strange solution that worked:

- Load up Nero 6
- Set the recorder as Image Recorder, open the .cue file, and RECORD it.
- A .nrg file will be created.
- Open this file with Alcohol 120%
- Success
