I’m using Jquery Plug-in FileUploader (BlueImp) to upload images. I want to allow the process of cancel one specific image from uploading.

I know that I can´t delete the image from the input (because is readonly), How can I do this ? 

$('#fileupload').fileupload({

                dataType: "json",
                url: "Handler.ashx?alp=0&bostamp=" + bostamp,
                limitConcurrentUploads: 1,
                sequentialUploads: true,
                progressInterval: 100,
                maxChunkSize: 17179869184,
                maxFileSize: 17179869184,


                add: function (e, data) {
                    var code = data.files[0].name;
                    var mlen = data.files[0].size;
                    var ftype = data.files[0].type;
                    var oktype = 'ok';
                    switch (ftype) {
                        case 'image/jpeg':
                            {
                                oktype = 'ok';
                                break;
                            }
                        case 'image/pjpeg':
                            {
                                oktype = 'ok';
                                break;
                            }

                                break;
                            }
                    }
                    //limita tipo de ficheiro jpeg
                    if (oktype == 'nok') {
