title: Dropzone Display existing files and edit already existing images
body: <p>I am using Dropzone js to upload images to my application. This works fine on the insert page but I need to be able to edit records and add or change already existing images associated with the record. The overall application is using Laravel.</p>
  <p>I used the following code to do this, the files are added, but when I click on the submit button, it says that there is no file.</p>
  <pre><code> myDropzone.emit(&quot;addedfile&quot;, mockFile);
   myDropzone.emit(&quot;thumbnail&quot;, mockFile, path);
   myDropzone.emit(&quot;complete&quot;, mockFile);
   myDropzone.files.push(mockFile); // added this line
  </code></pre>
  <p>My dropzone options :</p>
  <pre><code>            var options = {
              autoProcessQueue: false,
              maxFilesize: 5, // MB
              dictRemoveFile: &quot;Remove&quot;,
              addRemoveLinks: true,
              paramName: &quot;files&quot;,
              maxFiles: 6,
              parallelUploads: 6,
              uploadMultiple: true,
              acceptedFiles:&quot;image/jpeg,image/jpg,image/png&quot;,
              capture: &quot;image/*&quot;,
              previewsContainer: &quot;.dropzone-previews&quot;,
              clickable:'.dropzone-previews',
              thumbnailMethod: 'crop',
              timeout: 500000,
              myAwesomeDropzone : true,
              autoDiscover :false,
              init: DropzoneInitializeFunction,
              ignoreHiddenFiles:true,
          };
  </code></pre>
  <p>How would I do this?</p>
