Play with the "dragable layers/plugins" example from the Krpano download package. Anyway it must be modified to your needs. By the way, how is the layer dragged in your scheme? The hotspots stays still and the layer follows mouse or should hotspot and layer both move?
hello thanks for being attentive, but do not really understand the point
Might be more specific or give some example to understand better what you mean?
thanks
regards
