Can you tile windows from Javascript in CS3?

Question

I have a javascript that will open 2 images in Photoshop from different directories based on a single filename, so that the users can view them side by side. They need this to be able to compare the colour correction from an automated process against the original image.
The trouble is that even though I can open the images, I cannot invoke the "window/arrange/tile vertically" menu item, as I can with InDesign.
Does anyone know of a neat trick to get around the missing tile vertically command within Javascript for Photoshop CS3.
(I've trawled the web and found that most answers are for 4 or more windows, where the images are pasted into one doc. But here I need to keep the windows separate.)

Answer 1

One way to do this in CS3 is with an action. Make a new action then stop recording. There should be no steps in the action. From the action panel's flyout menu choose insert menu item. Then choose the "window/arrange/tile vertically" menu item. You now have an action that you can call from a scipt to tile the two images.
Another way is to use Xbytor's doMenuItem function
// adatped from Xbytor's xtools stdlib.jx
doMenuItem = function(item, interactive) {
   var ref = new ActionReference();
   ref.putEnumerated(charIDToTypeID("Mn  "), charIDToTypeID("MnIt"), item);
   var desc = new ActionDescriptor();
   desc.putReference(charIDToTypeID("null"), ref);
   try {
     var mode = (interactive != true ? DialogModes.NO : DialogModes.ALL);
     executeAction(stringIDToTypeID("select"), desc, mode);
   } catch (e) {
     if (!e.message.match("User cancelled")) {
       throw e;
     } else {
       return false;
   return true;
doMenuItem(stringIDToTypeID('tileVertically'));
Note newer version of Photoshop have a app method named runMenuItem that can be used instead of a custom function.
