title: Why processQueue in jQuery file uploader doesn't work here?
body: <p>I am using <a href="https://github.com/blueimp/jQuery-File-Upload" rel="nofollow">jquery file uploader</a>. I need files to direct upload from browser to Amazon S3. It is working fine with single upload with minimal setup of plugin. I need three sizes of same file need to directly uploaded to S3. So I think <code>processQueue</code> can be used for it, but didn't get it working until now.</p>
  
  <p>I am working file uploader in  requireJS environment. Below is the code, I tried. </p>
  
  <pre><code>$('.fileupload').fileupload({
      url: '//testbucket.s3.amazonaws.com', 
      type: 'POST',
      autoUpload: true,
      dataType: 'xml', // S3's XML response
      add: function (e, d) { console.log('add') };
      success: function (e, d) {},
      processQueue : [
          {
              action : 'loadImage',
              fileTypes : /^image\/(gif|jpeg|png)$/,
              maxFileSize : 5120000
          }, {
              action : 'resizeImage',
              maxHeight : 400,
              crop : false
          }, {
              action : 'saveImage'
          }, {
              action : "setImage"
          }
      ],
      processstart: function (e) {
          console.log('Processing started...');
      },
      process: function (e, data) {
          console.log('Processing ' + data.files[data.index].name + '...');
      },
      processdone: function (e, data) {
          console.log('Processing ' + data.files[data.index].name + ' done.');
      }
  });
  </code></pre>
  
  <p>These are modules I included in my requireJS module.</p>
  
  <pre><code>define(
      [
          'jquery', // jQuery Library
          'jquery.ui.widget', //  https://github.com/blueimp/jQuery-File-Upload
          'load-image',       // https://github.com/blueimp/JavaScript-Load-Image
          'canvas-to-blob',    // https://github.com/blueimp/JavaScript-Canvas-to-Blob
          'jquery.iframe-transport', // https://github.com/blueimp/jQuery-File-Upload 
          'jquery.fileupload',       // https://github.com/blueimp/jQuery-File-Upload
          'jquery.fileupload-process',  //https://github.com/blueimp/jQuery-File-Upload
          'jquery.fileupload-image'  // https://github.com/blueimp/jQuery-File-Upload
      ],
  </code></pre>
  
  <p>How to solve this problem?</p>
