Comment 2 for bug 884132

The "Create image" option is used to tell K3b that the ISO image should be created entirely on the hard disk before burning instead of being created "on the fly", not to "just create the ISO image". For that there is a checkbox named "Only create image" - select it and you'll notice that K3b will just create the image without burning it.

As this is not a real bug, I'm closing this report as Invalid. Feel free to report any other bugs you find.
