<!-- first I changed all double quotes to single
<!-- then I removed the quotes in front of the changeImages functions and after their return true; ...
<!-- then made sure there were no spaces in the changeImages function between the parantheses, even between quotes.
<!-- then made sure there was a single space in front of the onmouseover and onmouseout event handlers to delimit from other items
<!-- Then I added the document.write ("      ");  around each statement

document.write ("<img src='images2/banner3.gif' alt='banner' width='740' height='130' />");
