No, the assumption is correct, it's just that both Explorer 5 and Netscape 6 have trouble with preloading. A script like you wrote should work fine in the Version 4 browsers, but IE5 and NN6 are sometimes slow in showing images (though never in the same way, of course) and may request them from the server regardless (I think it's mainly IE5 who does this). So: it's a browser....not bug, more an inconsistency. ppk _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
