Have old dreamweaver site (2000ish) rollover images not showing up but it does in preview

Because you have condensed your code (all in one line) you have commented all of your JS out as per

<!--function MM_swapImgRestore() { //v2.0  if (document.MM_swapImgData != null)    for (var i=0; i<(document.MM_swapImgData.length-1); i+=2)      document.MM_swapImgData.src = document.MM_swapImgData[i+1];}function MM_preloadImages() { //v2.0  if (document.images) {    var imgFiles = MM_preloadImages.arguments;    if (document.preloadArray==null) document.preloadArray = new Array();    var i = document.preloadArray.length;    with (document) for (var j=0; j<imgFiles.length; j++) if (imgFiles.charAt(0)!="#"){      preloadArray = new Image;      preloadArray[i++].src = imgFiles;  } }}function MM_swapImage() { //v2.0  var i,j=0,objStr,obj,swapArray=new Array,oldArray=document.MM_swapImgData;  for (i=0; i < (MM_swapImage.arguments.length-2); i+=3) {    objStr = MM_swapImage.arguments[(navigator.appName == 'Netscape')?i:i+1];    if ((objStr.indexOf('document.layers[')==0 && document.layers==null) ||        (objStr.indexOf('document.all[')   ==0 && document.all   ==null))      objStr = 'document'+objStr.substring(objStr.lastIndexOf('.'),objStr.length);    obj = eval(objStr);    if (obj != null) {      swapArray[j++] = obj;      swapArray[j++] = (oldArray==null || oldArray[j-1]!=obj)?obj.src:oldArray;      obj.src = MM_swapImage.arguments[i+2];  } }  document.MM_swapImgData = swapArray; //used for restore}//-->

Either remove the comments or give the comments a separate line.
