Yes you can. To mount an ISO as a Virtual Drive there are
two ways of doing it:
Method 1: (I am feeling geeky)
1.Create a mount point for the iso image. How to do this? Press Alt and F2, and type
kdesu konsole
and press enter
Key in the root password and press enter
Type
mkdir /mnt/iso
and press Enter
This command will make a directory called iso (mkdir-get it

) in /mnt folder.
2. Mount the iso. Type the following command
mount -o loop -t iso9660 filename.iso /mnt/iso
and press Enter
In the place of filename.iso you have to give th ename of the OpenSuSE iso.
For example
mount -o loop -t iso9660 openSUSE-10.3-GM-DVD-i386.iso /mnt/iso
You will now be able to browse to /mnt/iso using Konqueror file manager and browse the dvd.
Method 2: (I am feeling lucky)
Lucky to be using Open SuSE

1. Download KIso from
here
2. Press Alt and F2, type kdesu konsole and press Enter. key in your root password and press Enter. Now browse to where your file is. If you do not know how to browse in shell try this method. Open Home using Konqueror or by clicking on the icon in the taskbar. Browse to where you saved Kiso. In the konqueror toolbar in that folder, click on Tools-> open terminal. Type su and press enter. Give the root password and press enter.
3. Install Kiso with the following command
rpm -ihv kiso-0.8.3-6.3.i586.rpm
and press Enter
If typing kiso-0.8.3-6.3.i586.rpm intimidates you (long long name), just type kiso and press the tab key once. It will auto complete for you. This is a feature of the linux shell, which can be used if you are in the same folder.
You will see the install progress. Press Ctrl and D to close the shell (konsole).
4. Right click on ANY iso image (suse in your case)->Actions->Kiso->Mount as virtual drive

You will see the mounted cd/dvd icon on your desktop, which you can browse
After you finish, to unmount, Right click on the iso image (the original one,not the one on your desktop!)->Actions->Kiso->Unmount virtual drive
