questa genera i popup quanti ne vuoi
ci sto lavorando perche quello che avevo trovato non va si spostano,
caso lo script sposta anche le immagini, e ritorna Y ,X, id della
cosa spostata

Tra l'altro mi sono reso conto ora che va su IE ma su Firefox no...
La console di Firefox non riconosce "event" del codice:

compatibile con Firefox?ciao M. |
