2° passaggio: Sostituisci <img src="placeholder.gif" che troverai a fine script con lo stesso indirizzo web dello sfondo della tua pagina

3° passaggio :Attivate lo script  con questa stringa gestore di evento onload <body> inseritelo di seguito funziona con il ricaricamento della pagina

   <body onload="Carousel()">

AlcunI parametri sono variabili vedi all'interno dello scritto. Per ottenere un lavoro come l'esempio inserisci lo script all'interno di una tabella
