Bridge CS4 - Image processing into subfolders

Question

Design Premium CS4
Bridge 3.0.0.464
XP Pro SP3
Problem: Image processing into subfolders
I have a folder with several subfolders containing JPG files.
I want to reduce the file size by reducing the quality.
I use the following to do this:
Tools | Photoshop | Image Processor
Bridge doesn't appear to have the smarts to traverse down into the subfolders i.e. one has to do each folder individually.
Is there a way to have Bridge image process down into the subfolders? Thanks in advance.

Answer 1

This is a job for Photoshop not Bridge, Bridge can not alter the JPEG settings.
This Photoshop script should do what you want if you are talking about normal JPEGS and not Save for Web.
#target photoshop
var imageFolder = Folder.selectDialog("Select the folder with JPGs to process " + $.getenv("username"));
var quality = prompt("PLease enter quality required 1-12 ",5);
if (imageFolder != null)  processFolder(imageFolder);
function processFolder(folder) {
    var fileList = folder.getFiles()
     for (var i = 0; i < fileList.length; i++) {
        var file = fileList[i];
  if (file instanceof File && file.name.match(/\.jpg$/i)) {
   open(file);
saveFile(quality);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);  
  } else
if (file instanceof Folder) {
       processFolder(file);
function saveFile(quality){
saveOptions = new JPEGSaveOptions();
saveOptions.embedColorProfile = true;
saveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
saveOptions.matte = MatteType.NONE;
saveOptions.quality = quality;  
var fileRef = new File(decodeURI(activeDocument.fullName.fsName));
activeDocument.saveAs(fileRef,saveOptions);
