Mount ISO image 0.7
This script and servicemenu allow you to rightclick an ISO image and mount it to a directory. While mounting systems which are not included to fstab is allowed only to root, you have to enter root password once the script asks for it. Script will create a folder on the desktop, where the iso image will be mounted to. You can mount several ISO images at the same time. The corresponding folder will be deleted automatically after unmountig.
+ Support for CloneCD (CCD/IMG/SUB files) - custom MIME type was added, so you can right-click
a cue file (".CCD") and convert the image file (".IMG") to a standard ISO.
This feature requires 'ccd2iso' utility, available here: http://sourceforge.net/projects/ccd2iso/

Good ehh ???

actually

sudo mount -t iso9660 -o loop /search/path/to/iso /mount/point

will do that just fine in knoppix.
otoh the script might flatten the learningcurve for beginners.
