In the previous post I mentioned repairing the barrel distortion some lenses have. That prompted me to remember this cool little free tool for making panorama images. Check it out. Easy to use, however if you are not totally comfortable working in your PC system area, get someone who is to install it for you.
For your convenience I have compiled the Windows version of PanoTools library that is available on SourceForge. Currently this version is a little old but stable. The Field of View limit has been increased to 1000° from the normal 160.
