ho modificato come da indicazioni la riga
T1=new Array("trail1.gif",38,35,"trail2.gif",30,31,"trail3.gif",28,26,"trail4.gif",22,21,"trail5.gif",16,16,"trail6.gif",10,10)
per lasciare solo un'immagine..
prendo l'esempio di un'immagine esterna a tutto, la scritta Google:
http://www.google.it/intl/it_it/images/logo.gif
modifico l'array cosi
T1=new Array("http://www.google.it/intl/it_it/images/logo.gif",276,110)
e funziona perfettamente in firefox, ma in IE7 no..
perchè?
PS..
avevo cercato con google, ma solo in italiano
