[Mac OSX / JS] How to find images inside sub folders using getFiles?

Question

Hi,
My script uses the variable myFolder to store the path for the images Folder. But when I try to use myFolder.getFiles() to retrieve images that are in sub folders the script fails. The result is null. What can I do to force myFolder.getFiles() to search inside all sub folders?
var myFolder = Folder().selectDlg("Select images Folder");
var myFiles = myFolder.getFiles();
I will appreciate any help.
Thanks,
Candido

Hi John,
Thanks for your help.
I'm rushing to my work  so I don't have enough time to sort it out at the moment.
If I understand you correctly, it should be something like so:
var files;
var folder = Folder.selectDialog( "Select a folder with images" );
if (folder != null) {
     files = GetImages(folder);
     if (files.length > 0) {
          alert("Found " + files.length + " image files");
     else {
          alert("Found no image files");
function GetImages(theFolder) {
     var imageFiles = [],
     fileList = theFolder.getFiles(),
     i, file;
     for (i = 0; i < fileList.length; i++) {
          file = fileList[i];
          if (file instanceof Folder){
               GetImages(file);
          else if (file instanceof File && file.name.match(/\.(jpg|psd|tiff|pdf|eps)$/i)) {
               imageFiles.push(file);
     return imageFiles;
But it doesn't work.
