I have made a panorama in PS CS5. Is it possible to export it to Flash in order to make an interactive Flash panorama, where I can pan around?
Not sure if you will be able to add interactivity or navigation controls through PS directly. I think you will need to provide the interactivity through flash professional. Here is one such example which might help: http://www.riacodes.com/flash/create-a-360-panorama-viewer-with-as3/
