salve a tutti! ho provato finora su un server windows con php5 questo codice e funzionava... mi faceva il resize di un'immagine prima come miniatura e poi come zoom e mi salvava le due nuove immagini in due cartelle sul server. Ora ho portato il tutto su un server linux con php5, ho dato i permessi di scrittura alle cartelle, la pagina viene eseguita tutta (mi fa anche le query di aggiornamento che sono in fondo a questo codice...) non mi dà nessun errore, eppure non mi crea le immagini!!!!
