Dear All, I've tried the demo version of krpano viewer for deskptop and iphone/iPad. It works well except for watermark. Before I plan to purchase a licensed one, may I know the water mark or big logo is still there? I also tried other panoramic viewer for iPhone, the licensed version also comes with big logo on the image presented. We decided not to use that software. I don't mind if the logo is small at bottom. Best Rgds. Ms. Zhu
