Align all pages to center

Question

I'm trying to edit hundreds of product images in fireworks with the least amount of repetition.
I have loads of variations of ratios that break the nice look on the website so I created a master page at the correct dimensions then mass import all images as pages, but then I have to align the images up to the center of the document. Its at this stage I'm repeating myself a lot. At the moment I'm going through each page selecting the image then aligining it up to the center of the canvas. I want to align all the images on each page to the center of the canvas without repating the steps like above.
Any ideas?

Hi Kricket;
try below code i check in cs6 version
var myDoc = app.activeDocument;
var myLayer = myDoc.layers;
var mycolor = myDoc.swatches
var myPage = myDoc.pages;
var flag=false;
var color=false;
myDoc.viewPreferences.rulerOrigin = RulerOrigin.pageOrigin;
var myY2 = myDoc.documentPreferences.pageHeight;
var myX2 = myDoc.documentPreferences.pageWidth;
var myPagesTotal = myDoc.pages.length;
checkLayer();
checkcolor();
placeFrame();
function checkLayer(){
for (var l=0; myLayer.length>l; l++){
    if (myLayer[l].name =="dieline"){
        flag=true;
    if (flag==false){
    var myNewLayer = myDoc.layers.add();
myNewLayer.move(LocationOptions.atBeginning, undefined);
myNewLayer.name = "dieline";
function checkcolor(){
for(var c=0;c<mycolor.length;c++) {
      if(mycolor[c].name=="dieline"){
          color=true;
// add dieline swatch and set parameters
if (color==false){
    var spotDie = new Array(0, 100, 0, 0)
    myDoc.colors.add({model:ColorModel.SPOT, space:ColorSpace.CMYK, colorValue:spotDie, name:"dieline"});
function placeFrame(){
for (var p=0; myPage.length>p; p++){
    var myBorder = myPage[p].rectangles.add();
   myBorder.move (myDoc.layers.item ("dieline"));
    myBorder.geometricBounds = ["0p0", "0p0", myY2, myX2];
    myBorder.strokeColor = "dieline";
    myBorder.overprintStroke=true;
    myBorder.fillColor = "None";
    myBorder.strokeWeight = "1pt";
    myBorder.strokeAlignment = StrokeAlignment.centerAlignment;
