I am looking for a software that can put many photos and form one big photo. Any idea?

Arcsoft has or had one called "PhotoMontage" or something like that. The biggest problem with it was the lack of images for the tiles.
This is the guy who REALLY knows how to do it, Rob Silvers … he did the "Truman Show" poster and most of the Newsweek and Time magazine covers, for example, but he hasn’t commercialized his software. When he was at MIT he had access to many terabytes of image files so his mosaics typically look much better than you can do with the commercial software and limited images for tiles
