Never mind - I downloaded gparted and booted to that. Held my breath the entire time, but everything is still there!

I am a newbie to linux, but Fog has been WONDERFUL for our school - if I wanted to choose option #1
“1. Increase the size of the partition on which /images is stored.”
which part of the Fog instructions would I use? I am afraid of losing what I have by doing something wrong.
I am running on VMware, and added the space to the hard disk there, I just need to know what to do to add it to my partition.

Thank you in advance!
