I thought you might like this one if you haven't as yet found it. My interest is photography and I do editorials on some software, so I am always on the look out for new ones or improvements on the old ones. The new image stitcher from MS called ICE is excellent. I have tried it several times and different types of images and for me its the number one of image stitchers. Not complex like Huggin which is not straight forward at all and is better than Autostitch. Here is an image I took some years ago. These are three 5mb jpg images..

Here is the link to ICE -
http://research.microsoft.com/ivm/ice.htmlIt has a download for 32bit and 64 bit Windows
The great thing also is that it has a variety of extensions you can save it as, even psd.
Like to know what you think as well.
