Witam oto moja strona http://www.pantera366.vooa.pl/ nieukończona oczywiscie.Skrypt polega na preloadzie obrazków.Chodzi mi o to żeby ten preload działa tylko przy wchodzeniu na stronę główną bo narazie działa on także przy przechodzeniu z podstron na strone głowna np z działu kontakt do home. Oto kod skryptu,skrypt nie jest mojego autorstwa wprowadzilem jedynie kilka zmianBede wdzieczny za kazda wskazówkę
