Because I wanted this page to stay in the same location and not be redirected, I used locationAfterPreload="#" instead of locationAfterPreload="your_next_page.html". To automatically redirect, use your_next_page.html for the next destination.
STEP 1/2: Put this code into the <HEAD> of your document:
<HEAD>
<script language="JavaScript1.2">

startingColor[0] = "2"
startingColor[1] = "9"
startingColor[2] = "2"
endingColor[0] = "2"
endingColor[1] = "9"
endingColor[2] = "2"
var gap = 8 // minim 2

STEP 2/2: Put this table into the <BODY> of your document:
<BODY>
<div align="center">
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse">

for (i = 0; i < num; i++) {
document.write('<td width="' + gap + '" id="cell' + (i+1) + '"></td>');
}
document.write('</tr></table>');
document.write('<p>')
loadImages();
// end hiding -->
