As Auster has said. stitching overlapping photos is the way to go.
The opening titles of this show
http://www.photodex.com/sharing/viewsho ... 3813&alb=0 have a photo at the top made by joining 7 overlapping photos together to give a 'wide angle' view. The second slide of the show (after the titles) is a 'pan' across this combinations of photos. The art is to use a tripod, or swing your body on the same axis, and make sure you have overlap, and no change in camera settings while shooting the series of photos. The 'overlap' between successive pictures is so that the software can merge the photos.
I use 'Panorama Factory' to stitch my photos, but there are many programs available. I believe Photoshop CS3 does it now, but not as successfully as dedicated programs.
