How can I show you the files already stored on server using Dropzone.js

Finally !!

$(function() {
    var mockFile = { name: "banner2.jpg", size: 12345 };
    var myDropzone = new Dropzone("#my-awesome-dropzone");
    myDropzone.options.addedfile.call(myDropzone, mockFile);
    myDropzone.options.thumbnail.call(myDropzone, mockFile, "http://localhost/test/drop/uploads/banner2.jpg");
})
