I am trying to use ISO images to install some stuff on my machine and i found it very strange that not many easy to use tools are available on web to read ISO files and use them. Most of the tools allow you to burn the iso image on a DVD and then use them. Now this is pretty time consuming process.
So i googled hard and found an unofficial tool from microsoft which can be downloaded from http://download.microsoft.com/download/7/b/6/7b6abd84-7841-4978-96f5-bd58df02efa2/winxpvirtualcdcontrolpanel_21.exe
Its probably unsupported from Microsoft but is very easy to use. Don't forget to read the readme file which you would get once you extract the exe.
So happy mounting the ISO images...
