There is no way to copy a Photosynth or panorama within Photosynth at this time. You can sign in and edit the one you have already created to French. But if you want a second panorama you will have to create it. If you used Microsoft Ice to create your panorama hopefully you saved your work and can publish to web rite from Ice. When it’s uploaded you will have to select your highlights all over again. Nice work, it looks great.
Good luck, Waldos Digital World
