Ok. One more time.
As long as you test for (document.images) nothing will go screwy.
The problem arises when you don't test for (document.images)

i.e. 

<HTML>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">

frame1 = new Image();
frame1.src = "http://www.blah.blah/frame1.gif";
frame2 = new Image();


.....However, if you use:

<html><head>
<Script Language="JavaScript" Type="text/JavaScript">
<!-- 
if(document.images) {

     frame1 = new Image();
     frame1.src = "http://www.blah.blah/frame1.gif";
}
-->
</Script>
</head></html>


..nothing will go wrong. Works every time (unless you use MSIE 2 or 3).
If you can prove to me that by using:

<html><head>
<Script Language="JavaScript" Type="text/JavaScript">
<!-- 
if(document.images) {

     frame1 = new Image();
     frame1.src = "http://www.blah.blah/frame1.gif";
}
-->
</Script>
</head></html>

that you get an error in NN4, or any other browser, I will sell my home and
move to
the Andies with a goat named Bob.
