K3B image file to audio CD question

Hi all,
Have asked this question on another forum with no response, and I suspect the answer is really simple but here goes anyway.
I was in the process of duplicating an audio CD, when my burner failed. So I created a .img and .toc file on the hard drive.
Now that I have replaced my burner, how do I recreate thses files as an audio CD. I would prefer to use K3B, but if I need to use the CLI then that is OK to.

TIA

I think there was a post about this at the usnet group alt.os.linux.mandrake

I can't remember the details, but you can google for it.

Good Luck!
Jeremy
