JPOnion,

Have a talk to the system administrator for the school in the IT section, explain the problem I am sure they will help you out. They more than likely have a machine that you could use there and burn the images to a CD for you. If you don't ask you won't get help. Most IT sections I have ever dealt with are more than willing to help out, when things are explained fully to them. They aren't that paranoid about programs where honest information is given.

The simplist thing to do would be to use the friends Laptop.

Good Luck.
