Kyn: Thanks for the suggestion. However, what I'm looking for is a sprite that allows the panorama image to loop back and forth for use in virtual tours. I am currently using software provided by PHOTOWARP which does the job but has some drawbacks. For example, it tends to load slowly and sometimes distorts the image while loading. I am also trying to find software that allows a vertical image, such as a tall building, to pan up and down.
