My Super-Simple Panorama Viewer
Click on the links under the picture to change the picture. Most are about 1 megabyte though so if your connection's slow you'll need patience. Scroll horizontally with the scrollbar.
The strips have different heights because this sort of stuff happens. The algorithm stitches pictures together by matching up control points in the pictures and then trims off the top and bottom. Things like not having the tripod level cause more to be thrown away. Also my one to the east I'm looking uphill on one side, downhill on the other so it only shows what's in common between the two. I bought a level and carefully levelled my tripod for this one.
